No doubt TSBGOD will just let this fly over his head but here goes this is some info pulled from an article...
EPA= Expected Points Added
WPA= Win Probability Added
"Peyton has 129 EPA in 19 playoff games at 0.16 EPA/play. Brady has 114 EPA in 23 playoff games with 0.12 EPA/play. That's 33% more EPA per game and per play than Brady.
Want to measure clutch specifically? Peyton has 4.1 WPA in the playoffs at 0.22 WPA/game, while Brady has 4.23 at 0.19. That's 16% more WPA/game for Peyton than Brady. If Peyton is a playoff choker than Brady is even worse, and that's simply an absurd premise.
How to account for their different playoff records then? Just look at Peyton's teammates and their contributions. In the playoffs the non-passing aspects of Peyton's teams have added *negative* 6.1 EPA/game while Brady's team have added +0.2, according to Jason Lisk and PFR"
"While that was a horrible game by the pass defense, it is not that atypical for Manning’s playoff career. Let’s compare him to Tom Brady, and here is a breakdown of various aspects and points added/lost by each phase since 2000 in playoff games (sorry, the loss to Tennessee in his first playoff game not included).
What does that show? Brady and the passing offense has been the primary driver of the Patriots’ playoff success, but the other phases have not hurt him in aggregate. Manning’s teams, on the other hand, have been worse in every phase, except for rushing defense, most notably in passing defense in the postseason. When both Manning and Brady are over 10.0 points added with passing offense, they are undefeated in the playoffs. (5-0 for Manning, 6-0 for Brady including yesterday). It’s what happens when they are not outstanding that has been the difference.
When the passing offense is merely above average (between 5 and 10 points), Manning is 1-5 in the postseason, with the one win coincidentally enough being the huge comeback against New England in the AFC Championship game that, temporarily, reversed the narratives. Brady is 3-1 when putting up similar performances, the one loss being last year’s Super Bowl.
Peyton Manning’s performance on Saturday, by this measure, was exactly in the middle of his past playoff performances–10th best in the postseason. Being exactly in the middle, thusly, means a loss. The special teams provided a boost, but it was more than offset by the defense. Manning should be judged for the specific plays he does and does not make, but when it comes to citing quarterback wins and losses in the postseason, realize that it is tied to many other things. Don’t let kicks, and misses, and shoe string tackles, and safeties blowing coverage define it"
