Welcome Back

The 2010 season starts tonight, and Advanced NFL Stats returns in mid-season form. I'm going into a contract year, and I'm in the best shape of my career. I had a great off-season working out at the team facilities. I've finally put my messy personal problems and last year's four-game suspension behind me, and my coaching staff is expecting big things. So draft Advanced NFL Stats first and put it #1 in your RSS reader.

The Win Probability graphs will be going strong again with a few enhancements. The model has been tweaked, with more refined estimates when the ball is near the goal line. I’ve added a live update of the Expected Points of the current drive. It’s a little abstract, but it gives a feel for the impact of events in the game. (That sack on 3rd and 4 just cost us 3 net points!). I also plan to add the current probability of a TD and probability of a FG at some point.

Also, during the last couple weeks of the playoffs last season, I added a live chat/comment capability under each game’s graph. We had a lot of fun with it, and I’m bringing it back this season. The chat from last year’s Super Bowl was great with all its twists and turns. I don’t expect every game to get flooded with instant commentary and analysis, but for the bigger national games I know readers will add their two cents.

The Linebackers' Dilemma

Say there are two inside linebackers on the same team, John Andrew and Dan Farley. They’re considered equally good players, and both are in a contract year. Their team is good, and one of the early favorites to go deep in the playoffs this season. Each one has some choices to make over the course of the upcoming season.

Both Andrew and Farley want a big payday. In order to get as big a contract as possible, they need a lot of gaudy numbers to point to—lots of sacks, QB hits, forced fumbles. Millions of dollars are on the table, and the temptation is strong. However, leading their defense to a successful year and going deep in the playoffs will increase their values too. But that can only happen if both Andrew and Farley play selflessly and put their team first.

On any given play, a LB can either guess at the play call, trying to get a sack or stuff a run. Or, he can play his responsibility within his scheme by reading and reacting, doing exactly what the coordinator expects him to do. In other words, he can do what his team is counting on him to do, or he can gamble trying to make a play himself, exposing his team to giving up big gains.

Washington Post: McNabb's Potential Impact in DC

Today I'm beginning a weekly contribution at the Washington Post's Redskins Insider site. Well, it will be weekly as long as the commenters don't have their way. (There's a little "Report Abuse" link next to each comment, and I think I might have to report almost every one. Maybe readers were expecting another riveting Albert-Haynesworth-is-lazy post.) My contributions will be primarily Redskins-specific, but will draw upon the general concepts in the Advanced NFL Stats toolbox.

The inaugural post is a back-of-the-envelope calculation about how many wins McNabb can bring with his expected passing efficiency and turnover rates. Of course, there's more to a passing game than just a QB, but this gives Redskins fans an idea of the range of potential improvement.

My thanks to Lindsay and Mitch at the Post for the opportunity. Looking forward to a fun season.

The Weekly League: Notes and Ideas for Week One

Five notes before we begin:

1. Thank you times a thousand to Brian Burke. His site is crazy good. It's my ambition not to destroy it.

2. Below are previews of two upcoming games: Thursday night's between Minnesota and New Orleans and the Monday game between San Diego and Kansas City. These previews aren't intended to be exhaustive, by any means. (In fact, the attentive reader will notice that there are only, like, 10 words dedicated to the Chiefs.) Rather, the intent is to construct a lens through which to watch these games -- hopefully something that your local paper isn't gonna provide. I discuss this more fully in the introduction thing near the end.

3. Oh yeah, there's an introduction thing ("Introduction-as-Epilogue") near the end of this document. It explores more fully the theoretical underpinnings to this document. If it makes you throw up, I apologize.

Site News: Welcome Carson Cistulli

On other sites and message boards I often see Advanced NFL Stats referred to as “the Fangraphs of football.” That’s a pretty high compliment, and although I wouldn’t go nearly that far, I’ll certainly take it. There are a lot of similarities, and they were mostly accidental, at least at first. Both sites feature sound statistical analysis, and both feature live win probability graphs for their respective sports. After my own WP graph feature gained a following, I looked at Fangraphs for inspiration for how to further build a respectable sports analysis site. Gradually, Advanced NFL Stats became Fangraphs’ creepy stalker Jennifer Jason Leigh character from the movie Single White Female, and now the transformation is complete.

Carson Cistulli, a regular contributor at Fangraphs, has agreed to come on board to provide us with his brand of analysis, a slightly more entertaining look at football stats than what I can normally provide. He’s planning to start off doing some game previews, but may do some other things down the road.

Aside from his regular gig at Fangraphs, Carson is a writing instructor (maybe he can help me), a contributor at RotoWire, and a real-life poet. Yes poet. (Warning. Click at your own risk.)

So please welcome Carson, and you can look forward to his first post shortly.

Risk Taking In The NFL

Judy Battista, the New York Times national NFL correspondent, just did an article titled Coaches Take More Risks, but Perhaps Not Enough. I helped do some of the analysis for the piece. David Romer is also interviewed.

Navy 4th Down Strategy

Navy plays a triple option offense, a somewhat rare scheme even in college these days. The triple option allows Navy to compete against much bigger and faster opponents using discipline and execution as their weapons. They tend to be at or near the top of all Division I (FBS) schools in running every year, partly because they rarely pass and partly because they run the option so well.

Navy has enjoyed tremendous success in recent years, especially for a school that offers its recruits a rigorous and austere lifestyle, an extremely challenging curriculum, and virtually no chance of an NFL career. Last year they won 10 games, including their second win over Notre Dame in three years and a 35-13 drubbing of Missouri in the Texas Bowl. It was their seventh consecutive winning season and seventh consecutive bowl appearance. QB Ricky Dobbs broke Tim Tebow's record for rushing TDs by a QB last season. As my favorite Navy blog put it, archrival Army looked at their two-touchdown loss to the Midshipmen last year as a cause for optimism.

One thing about option football is that there is always a very good chance of a gain of at least a few yards. There aren't sacks or incomplete pass attempts. Navy always seems to be able to gain at least 2 or 3 yards when they need to, even when the defense knows exactly what is coming.


Navy's kicking game isn't anything special, to put it kindly. Their place kickers and punters don't have nearly the range and accuracy of the those at the top schools, much less the NFL.  Plus, Navy needs an edge against the bigger and faster opponents they typically play. So my theory was that Navy would be the perfect team to implement an aggressive 4th down strategy.
