Possible reason for Manning's failure in playoffs

[legendary loser]

People might know this already, but I'll throw this out there anyway. Since the San Diego game, everyone has been saying Peyton Manning has trouble when under a lot of pressure. This is no suprise as most quarterbacks will have similar problems. One thing about the playoffs is intensity and the speed up of the game increase. Peyton is horrible when blitzed, if he doesn't have time to sit in the pocket he's almost helpless. In yesterdays game, the majority of Peyton's long completions came when the Steelers rushed 3 and dropped 8. The Steelers went back to blitzing when it was 21-18 and the came up with 2 quick sacks. I'm aware that Pittsburgh blitzes almost more than most teams, but I'm skeptical if Peyton Manning can succeed (win a SB) under the intensity and speed of playoff games.
