Good point. You might be interest...jim campasano--<br /><br />Good point. You might be interested in the Coefficient of Variation, where the standard deviation is divided by the mean to get a "unitless" measure of volatility:<br /><br />CV = SD/mean<br />http://en.wikipedia.org/wiki/Coefficient_of_variation<br /><br />In fact this is what Anonymous calculates above--see September 17, 2009. (Note: I think there is an error in Anon's calculations: "Underdog of 10+ 59.2%"; it seems to me that the percentage should be 9.7/19.5 = 49.7%. Also, there appears to be rounding error on a couple calculations; I suspect that Anon is calculating with more significant digits in the mean and SD than he/she posts.)<br /><br />It's worth pointing out that Anon's numbers are very similar to the author's: SD's of a little more than 10 points for big favorites, and a little less than 10 for underdogs. Anyway, Anon points out that there does appear to be a slight trend toward higher CV's for bigger underdogs (the underdogs have smaller SD's, but they have smaller means also).<br /><br />However, does this indicate a difference in strategy between the two populations? No; there may be many explanations for the apparent difference in CV's, not least of which is that the same level of randomness would necessarily have a greater relative effect on a team with a smaller mean. (The difference between a touchdown and a field goal is a big RELATIVE effect if your mean is 14; not as much of a relative effect if your mean is 35.)<br /><br />Upon reflection, it's not clear to me that either the CV or the SD is really a good way to measure a team's strategy. However, I do agree with the author and with several individuals above that underdogs should attempt to do two things:<br /><br />1) Limit the total number of possessions (to increase the effect of randomness). Since the clock is fixed, this is equivalent to increasing the average time off the clock per drive.<br />2) Adopt a high-risk, high-reward strategy (again, to give randomness an increased role in the game's outcome).<br /><br />Unfortunately, it is hard to think of strategies that do both. For instance, throwing deep is a high-risk, high-reward strategy that amounts to throwing the dice and betting a lot on the outcome of a single play, so it may be a very good approach to Goal 2, but it is a very poor approach to Goal 1: deep passes tend yield a lot of incompletions, which stop the clock, as well as sacks, interceptions, and quick touchdowns, none of which will tend to achieve Goal 1. (Note: obviously quick touchdowns are great...but by definition they do not take much time off the clock.)<br /><br />For the favorite also, it's hard to come up with strategies that achieve the OPPOSITE of both goals: conservative, low-risk play-calling means runs and short passes, but these tend to result in long, grinding drives and lots of time of possession (which results in fewer possessions per game, exactly what the favorite does NOT want).<br /><br />However, there is room for a few observations. A favorite can benefit from running a no-huddle hurry-up offense most of the time...assuming that their offense will be just as effective without huddling (a big assumption). And a weaker team should generally take as much time off the clock between downs as possible. Also, as a lot of others have already pointed out, an underdog should be willing to go for it on 4th down in a lot of cases; this type of strategy could help to accomplish both goals.<br /><br />Often an underdog can grind it out, make it a low-scoring game, and hang around within striking distance of the lead for the first three quarters or more, and then bet the whole game on a single drive at the end. In many cases, that may be the best they can hope for. If so, this might give an alternative explanation for why an underdog would play conservatively until the end: maybe it's not that they're irrationally ignoring Goal 2, but are rationally pursuing Goal 1 (this strategy would be rational to the extent that Goal 1 was deemed more important than Goal 2, which has yet to be determined).mathmandanhttps://www.blogger.com/profile/16636227698860566596noreply@blogger.comtag:blogger.com,1999:blog-38600807.post-63493285615394378252013-01-08T17:08:16.534-05:002013-01-08T17:08:16.534-05:00I would expect SD to be lower for teams who are bi...I would expect SD to be lower for teams who are bigger underdogs simply because I expect them to score less.

Problem with game theory and Nash equilibrium is with a low sample size people are fooled by randomness. In reality there is a lag time towards adjusting... Thus higher care piece towards end means opponent can't adjust.<br />If you have a really good play against a defense and can keep the game within a TD that play the first time you try it might work 80% of time. Opposing team will then be able to counter on offense with re,wining time but if you already have tried play the better team will get aggressive if need be, gain a lead and counter your strategy. After you have tried a trick play or carefully designed play its success rate may drop to 60% and then 40%.

Everyone knows the universal truth of the first side of the coin that says that a team that scores more points than the opponent always wins. What people don't know is how a team lost a game without factoring the score. The other side of the coin would say that the team with the most real turnovers always losses the game. Statisticians do not count all events that turn the ball over without first scoring atleast 6 points. If they did they would see that the team with the higher number always losses. Try this with any game and you will see that it works:<br /><br />Complete Turnovers: Interceptions, fumbles lost, missed fg's, punts, 4th down fails, kickoffs lost, safeties, and turnovers due to time (given if the team in possesion at the end of the half failed to score and has to kick to start the second half. Not counted if another turnover half or whole occurs at the same time. Also when the game ends and the team trailing fails to score before the time expiresn not counted against the team with the lead. also nullified if another turnover takes place.<br /><br />Half Turnovers: Failed extra point or 2pat, Successful field goal, 2point conversion allowed.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-78423183619711694032009-12-07T09:00:12.717-05:002009-12-07T09:00:12.717-05:00In a year when the NFL is being dominated 300-400 ...In a year when the NFL is being dominated 300-400 yards through the air a game, with the #1, currently 12-0 team in the nfl having the league lowest rushing totals (though also tied for the league's 2nd most rushing points), while some of the bottom-feeders like the Raiders seem to do nothing, and lose (except to the steelers o.O), and dothers like the Rams and the Bills try to throw the ball and be aggressive all day get nowhere...<br /><br />I think we have ourselves an anomaly =]<br /><br />Or...The points here aren't as accurate as they initially seem.<br />Oh sure, I could see looking at your avg/rush, distance to 4th down, and 4th down conversion rate and realizing it'd be prudent to go for it a few times you'd have never thought of it before, however...<br /><br />This entire article Seems to indicate that Aggression in a game creates scoring and Conservatism limits it on both sides of the ball.<br /><br />I would suggest that "aggression" is probably not going to win an underdog a game, in fact, if they are the less talented game, it will probably just make it worse. <br /><br />For example, Let's look at the Lions and the Colts. Colts would be a huge favourite, so according to this article, the right thing to do would be for the Lions to play as aggressively as possible, passing deep, avoiding burning the clock, so maybe go no huddle, don't really run the ball if you can help it, except in very short yardage situations, and trust your defense to keep up as you keep them on the field for half a quarter longer than your opponent. <br /><br />Further, in order to safeguard themselves, the Colts should play conservatively. Huddling between run plays to run the clock, and not putting pressure on the lions qb, favoring zone coverages instead.<br /><br />Ideally, that should work, right? Except, this article completely ignores the dynamic matchups that decide NFL games. The Colts have the #1 passing game with the Last ranked running game, while the Lions are bottom last at defending against the pass, and are in the bottom quarter of the league for passing it themselves, combined with their inability to convert on 3rd down, and an even worse 4th down percentage, and 10 giveaways in 12 games, I really don't think they'd be giving themselves any chance whatsoever to win this game, but the Colts would also be inexplicably toning down what they do best in favour of what they do worst. <br /><br />Of course, this is about as an extreme of a contrast as you can get between two teams, but that's why I used it to illustrate the one-dimensionalness of "agression" vs "conservatism" as defining strategies.<br /><br />Instead, it's about getting the edge on a mismatch and exploiting it, that's what wins games. So for an upset to occur, the underdog has to find an unexpected exploit, and push it all they can, and hope it's enough. Sometimes, sure, it'll be a hole in their coverage zones that throwing it deep will exploit, or it'll be a bad matchup on the corner with your RE, and you'll play more aggressively on both sides of the ball. Or maybe, it'll be that the Colts' run efense is in the bottom half, and the Lions can chip away at them by running it up the middle. Would it be enough to win? Probably not, but the point is, throwing the game plan away straight away in favour of some ideal is *not* going to work. You have to stick in it as long as you can and keep hoping to find that edge that'll prove you're /not/ the underdog in the matchup, or to realize that you were called the underdog for a reason, and you're going to lose.<br /><br />=]Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-12804224389133725932009-11-25T15:43:54.205-05:002009-11-25T15:43:54.205-05:00In other words, point expectation on an offensive ...In other words, point expectation on an offensive or defensive possession is based on the underlying 0/3/7 score probabilities. Much as it seems to make some intuitive sense that ostensibly risky strategies such as blitzing and throwing deep should simultaneously raise the probability of scoring/allowing either 0 or 7 points on a possession, this doesn't make sense unless there's a compensating decrease in the probability of 3. While this may indeed be the result of such strategies to some degree, it seems as if it would apply disproportionately to play selections near the edge of field goal range. And these strategies still suffer the drawback of tending to increase the number of possessions, so it's really not clear to me that their use tends to benefit the underdog at all. In any case, I think it should be made clear in the article that the prescription applies primarily to this region of the field. Otherwise, it looks as if we're just superposing mathematical models onto the question without considering how they actually interact with football reality. <br /><br />I guess the other thought process to take into account is that these strategies might be affecting the transition probabilities: we take a bigger risk of incurring a field position deficit - thereby increasing the opponent's probability of scoring - in order to raise the probability of scoring ourselves. But I'm not sure that this really makes a difference. We're operating under the hypothesis that expected net points are not changing as a result of this strategy, and this is ultimately comes back to the 0/3/7 probabilities on offense and defense. Maybe the key intuition is that a given net point differential is less significant, in terms of pythagorean win probability, as the total number of points increases, so it makes some degree of sense for an underdog to aim in this direction. Though I still think this runs into the objection that increasing the number of possessions, when facing an expected deficit per possession, can never be a good thing.<br /><br />I know I'm kind of thinking out loud here, but I'm really trying to understand why this conclusion would hold true, and not quite getting it yet.Daniel Jepsonhttps://www.blogger.com/profile/15702100555332607012noreply@blogger.comtag:blogger.com,1999:blog-38600807.post-89240384275719871022009-11-24T17:44:33.053-05:002009-11-24T17:44:33.053-05:00With all due respect, I'm not sure that I buy ...With all due respect, I'm not sure that I buy some of the conclusions in this article. As others have noted, there are two components at work here when we talk about overall point variance: the variance of points in a possession, and variance in the number of possessions in a game. It seems that strategic decisions will primarily affect the latter category, and if we assume that higher-risk strategies tend to produce more possessions per game, then this works to the detriment of the underdog. (The converse of this is yet another reason why New England's refusal to go no-huddle in the SB was so baffling.) <br /><br />Unless I'm missing something, it doesn't really make sense to speak of a team deliberately raising their standard deviation of points per possession, with the specific exception of strategies that will minimize the probability of a field goal without affecting overall point expectation. With that in mind, I certainly agree that underdogs should be more inclined to play for a touchdown instead of a field goal when it comes to fourth-down decisions, and play-calling near field goal range in general. But what does an underdog gain by blitzing and throwing deep? Either these plays increase point expectation, in which case they should be doing them anyway, or they will merely tend to raise the number of possessions in the game, in which case they are playing into the hands of the opponent.Daniel Jepsonhttps://www.blogger.com/profile/15702100555332607012noreply@blogger.comtag:blogger.com,1999:blog-38600807.post-42022473217711946702009-10-12T12:25:28.184-04:002009-10-12T12:25:28.184-04:00Quick question based on yesterdays Cowboys/Chiefs ...Quick question based on yesterdays Cowboys/Chiefs game - what do your statistics say to you about going for the two point conversion versus kicking the extra point to tie the game (as the chiefs did with :24 remaining). I was somewhat surprised they didn't go for it, especially considering they were 0-3 at the time and a significant underdog. So my question incorporates the general statistical advantage of playing for overtime at home (questionable at best) versus the straight statistical probability that the offense can gain two yards on 4th down. Given the complexity of probabilities in playing for the tie and the dependency of those probabilities on outcomes not under your control (coin-flip), wouldn't ANY team be better off in this instance simply attempting the two point conversion?

Against their lousy divisional foes, the Cards were much more conservative than against the non-divisional opponents. They suffered numerous blowouts which caused pundits to see them as less capable of defeating elite teams than they actually were. In fact, their high risk/reward strategy prepared them beautifully for the playoffs where you must defeat a number of elite teams consecutively.<br /><br />This is where teams like Baltimore and Tennessee tend to struggle. Their conservative approaches, which work so well during the regular season where most of their opponents are inferior, do not prepare them for the playoffs. The Steelers appear to be a similar team, but their QB/WR situation is much better suited for the risks often necessary in the playoffs.<br /><br />Part of what makes the NFL so interesting also makes drawing conclusions from articles like this difficult. There are so many moving parts. However, it is worth noting that sometimes increased risk can dovetail with apparently counterintuitive strategies like slowing the pace. When an underdog goes for it on fourth down, that is in apparently risky strategy, but, when successfully executed not only allows them to retain possession but also succeeds in reducing overall possessions.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-21659818292815470732009-06-04T11:37:22.764-04:002009-06-04T11:37:22.764-04:00Although the high-variance strategy produces wins ...Although the high-variance strategy produces wins more often for the underdog, doesn't it also produce more heavy losses? <br /><br />Coaches might be worried about the morale effects on the players of a heavy loss (and not just the effect on the fans and the owners!)ukfannoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-50836919651535144672009-05-30T10:56:58.162-04:002009-05-30T10:56:58.162-04:00Michael-I agree.

With that said, the same said offense should then, as you said Brian, throw deep more often, run trick plays, perhaps use more unusual formations/motions/formation shifts, etc. but that the actual tempo of the game should be fairly slow.<br /><br />I would be interested to look at teams during what would be deemed a dynasty era that "overachieved" early in their dynasty run (and see how their use of the no-huddle compared with that of their more dominant years later on. I am willing to beat we would see a faster tempo from the more talented team than the early team.<br /><br />For example, the 2001 Patriots were, by most standards, considered a team that had mediocre, 8-8 type talent on their roster that went on to win a Super Bowl. I would be willing to beat that the 2007, 16-0 Patriots who were eventually upset by the N.Y. Giants ran the no-huddle significantly more than did the 2001 Patriots...ditto the 49ers of 1989-1990 versus 1981 (first championship of that dynasty, also won by a team considered not overly talented). <br /><br />As both Bill Walsh understood and Bill Belichick understand the value of analysis of tendencies (both their own and the opposition's) and metrics in determining strategy, I bet both dynasties would provide interesting support for the no-huddle variance strategy I am speaking of.Michael Schuttkehttp://www.nfldraftdog.com/nfl-team-columns/atlanta-falcons.htmlnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-48278676186254173782009-05-29T00:25:31.256-04:002009-05-29T00:25:31.256-04:00In order to observe the variance in strategy based...In order to observe the variance in strategy based on point totals, I'd think you'd have to adjust for the fact that among mismatched teams, the strategies will likely change due to the current score as the game goes on. So it may be that if heavy favorites become more conservative later in the game as they build a lead (and thus underdogs take more risks) the numbers shown in the last table may actually understate the early-game strategic inefficiencies. However, as others have suggested, there might be other in-game strategy changes that affect the results.<br /><br />Also, while I agree that in theory favorites should be more conservative off the bat and underdogs should take more chances, I don't think anyone has a clue how to modify your team's level of risk-taking without significantly changing your average point-scoring ability. In other words, by increasing its SD to 15 by employing a high-risk strategy, the underdog in your example may be reducing its average points to something so far below 17 that it becomes counterproductive. Recall that the Sackrowitz Chance paper on ball control offense found that the probability of winning is so sensitive to changes in scoring efficiency that underdogs attempting to deviate from optimal pace will likely reduce its ability to score too much to make the strategy worthwhile.<br /><br />If you somehow defined "conservative" and "risky" decision making, you should be able to show using historical data that underdogs that took more chances did indeed increase their odds of winning (even unintentionally). And vice versa for favorites. But I'd bet that such an effect wouldn't show up empirically because the margin for error is so thin.<br /><br />And of course, this is all complicated by overwhelming evidence that, when it comes to 4th down decisions anyway, teams don't make optimal choices in neutral situations to begin with.Jim Anoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-10790783430907589202009-05-28T11:58:33.397-04:002009-05-28T11:58:33.397-04:00I seem to remember them being much better than a "...I seem to remember them being much better than a "normal" sixth seed.

If this is an indication of being an underdog (and they were, given they were the 6 seed), then maybe we're on to something for sure.Justinhttps://www.blogger.com/profile/00527850321812906680noreply@blogger.comtag:blogger.com,1999:blog-38600807.post-9623299102911374672009-05-28T10:14:41.277-04:002009-05-28T10:14:41.277-04:00They definitely scaled back when Maddox got hurt b...They definitely scaled back when Maddox got hurt because of Ben's inexperience.

I should've said that the Steelers won the Super Bowl in 2005.<br /><br />While it's true that the Steelers, like most teams, run more when they're winning, I really think they tried to throw more in general with Maddox in 2002-2003, and Cowher did say that he wanted to build a more pass-heavy offense during that time. With the arrival of Big Ben, they switched back to a more conservative offense. Whether that was a choice based on the theoretically ideal strategy or a practical one based on having a young QB, I can't say. Probably some of each.Anonymousnoreply@blogger.com
