This is simple, crude and full of misconceptions I'm sure. But only Marino and Peyton are in no man's land on the losing side of it. There are some outliers. Starr obviously.. Brady's regular season Win % is so phenomenal that even winning over 700% of his playoff games is a dropoff. Staubach and Montana also suffer small dropoffs due to incredible reg season numbers. I personally hesitate to include Warner and Aikman in this group but both are Super Bowl champions with excellent post-season performances so they are in. Tarkenton, Eli, Warner and Aikman are the only QB's with sub-600 win % in the regular season. It helps inflate Eli, Warner and Aikman's postseason increase. And at the bottom by a wide margin you find Marino and Manning. I'm not hating on Marino for never winning a SB. He was one of the 4 greatest QB's of all-time. But he and Peyton have for whatever reason really struggled in postseason play.
Peyton is 3-4 in Wildcard Games, 3-4 in Divisional games, 2-1 in AFC Champ games, 1-1 in SB.
