How can I reconcile that fact with the claim that Brady has improved?</em><br /><br />Brady "carried" the Pats to three SB titles with an average EPA rank of 13th (50.5) and EPA/P rank of 14th (0.093) in those years. (It seems to me that he was entirely human back then too.)<br /><br />He's on course to average 3 times as much EPA, 150, during 2009-2011. That certainly is consistent with his having improved significantly. But, of course, one must consider how much this increase in his numbers has resulted from change in the quality of his teammates and in the team's style of play. <br /><br />From 2006 to 2007 Brady's EPA rocketed up from 84.3 (9th) to 267.3 (1st, and 103 points ahead of #2!) while his EPA/P zoomed up from 0.14 (6th-7th) nearly tripling to 0.40 (1st, and far ahead of Peyton's #2 at only 0.29). One suspects that the bulk of that resulted from the arrival of Moss, Welker and Stalworth, rather than Brady suddenly getting so much dramatically better all by himself. <br /><br />Factiod: In 2008, with Moss, Welker, etc., Cassel (after not starting a game since high school) had EPA of 104.7 and EPA/P of 0.17, both significantly higher than Brady in 2006, pre-Moss and Welker. Though rookie Cassel was *hardly* a QB of Brady's quality. More evidence about the degree to which the QB's numbers are created by his teammates. <br /><br /><em>Since 2007, Brady has gone from great quarterback on a fantastic team to the engine which powers otherwise mediocre squads to division titles.</em><br /><br />It is certainly true that pre-2007, and with the three SB winning teams, the Pats were a *good balanced team* with the Belichik D generally ahead of the offense, and the O being good enough. And since 2007 the Pats have become a throwing machine, with the rest of the team pretty much falling away.<br /><br />So yes, if Brady fails it's over for them. OTOH, how much of Brady's recent annual 150 EPA is due to him improving so much, and how much to Belichick converting the Pats to a throwing machine, is something of an open question. I'll buy that he's a good bit better than in his two-digit EPA years (SB titles notwithstanding -- teams win SBs) but I wouldn't say by how much.Jim Glassnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-52377656732851268292011-11-09T22:41:27.711-05:002011-11-09T22:41:27.711-05:00Very nice graphs.

Between his 17th and 32...Very nice graphs. But...<br /><br /><em>Between his 17th and 32nd pass attempted, Brady's passes decreased the Patriots' expected points by a whopping 10. In what eventually amounted to a four point game ... one could argue this cost the Patriots the game...</em><br /><br /><em>Brady almost did win it -- credit the Patriots defense for keeping it close. But the second and third quarters in particular were very unlike Brady, as he spent much of the middle part of the game hurting the team instead of helping.</em><br /><br />OK, the running game didn't get going -- but did any other players on the offense contribute to helping or hurting the Pats' passing game? <br /><br />When I read game analysis like this that is all QB, QB, QB, I can't help but recall the PFR.com analysis that attributes 28% of passing yards to the QB and wonder if I am missing 70% of the story. <br /><br /><em>With the Jets defeating the Bills on Sunday, the top three teams in the AFC East are separated by all of one game.</em><br /><br />No, they are all tied.Jim Glassnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-89958115583778564132011-11-09T14:57:39.142-05:002011-11-09T14:57:39.142-05:00Really cool.

My first thought was maybe this was all the times that Brady had played against the Giants, given that the title of the article was about how the Giants have Brady's number.<br /><br />To the author, sorry if my comment seemed harsh. Everything always "sounds" worse when it's written down.<br /><br />I'd be curious to know which plays decreased Brady's EPA the most. Was it sacks from the Giant's vaunted d-line? Picks? Drops? Checkdowns the went nowhere?Ian Bnoreply@blogger.comtag:blogger.com,1999:blog-38600807.post-26029995491257670602011-11-09T12:35:08.370-05:002011-11-09T12:35:08.370-05:00Steve - Easy, the Patriot defense is much worse th...Steve - Easy, the Patriot defense is much worse than it was in the early 00s.<br /><br />Ian - The top half of the graph is showing the total passing Expected Points Added after each passing play. For example, during the game represented by the light blue line the passing offense added about 7 points of EPA by the fifth passing play. The lower half of the graph is the same information but on a per play basis.<br /><br />That said, I agree that it is difficult to determine which game is which and a key would be very helpful here.<br /><br />It appears the red line represents the Giants game as it matches the description of dropping 10 EPA from plays 17 to 32, as it dropped from 0 EPA to approximately -11.<br /><br />Looking at the lines, I'd guess the light blue line is the Bills game as the large drops match the multiple interceptions Brady threw. The orange line is the Dolphins game as the large drop in the middle is Brady's interception after halftime, and the jump right at the end is the 99 yard TD pass to Welker.<br /><br />From there it seems like the lines are color-coded according to each opponent: yellow is the Chargers game, green for the Jets, dark blue is the Cowboys, black is the Steelers, and gray is the Raiders (it's not labeled victory or defeat, and it appears to end at play 36).Jameshttps://www.blogger.com/profile/01838293735141324662noreply@blogger.comtag:blogger.com,1999:blog-38600807.post-82023437427236109372011-11-09T12:07:54.525-05:002011-11-09T12:07:54.525-05:00The Pats missed the playoffs in 2002.
