That's the bottom line on Peyton. He's the best regular season QB ever. But in the post-season, he's very average and usually makes big mistakes at inappropriate times.
And don't tell me the int wasn't Peyton's fault. Just don't.

if Manning is 35 yards from all the glory if he scores there, he's also 65 yards from infamy..
and even if Manning and the Colts score, there's
WAY too much time left on the clock form Brees ( probably 1.25 or so)..
and who's to say whether or not Colts win the coin toss in OT, or score on first possession?
this assumption that Manning would have been immortalized with a TD there is ridiculous..it would not have given the Colts the win, they merely would have tied the game!
Big Ben is what, 8-2 lifetime postseason? 2 SB wins?
Bart Starr 9-1 lifetime postseason..
heck, Elway was something like 14-8, Brady is off-the-charts good in postseason...
not only was Manning 9-9 in postseason to date, he also left the playoffs 5 seasons in one-n-done fashion, i.e., losing in his first playoff game of the season, 5 times! many of those times the Colts had homefield advatage or at least a bye..how can that happen??
let's be fair , here.Manning, since switching to AFC South, has played against an expansion team in Houston, a lousy Jags team, and a Titans team that has just 4 winning seasons since 2002 ( above .500 that is).
his SB winning 2006 Colts team can't possibly be considered among the all-time great SB winning teams, right? I mean, do you think the '06 Colts could have beaten the '86 Giants? '85 Bears? any of the Cowboys teams from the 90's? any of the Niners SB teams? Patriots? how about the late 90s Rams?
or Favre's Packers? or Elways back-2-back SB winning Broncos? or the great Redskins teams of the 80s/90s?
not a chance...
