Erm, yeah. Thanks for stating obvious facts. Manning is the better quarterback, period. Sure, he's choked in the playoffs, but that still doesn't make him less of a QB than Brady.
In a few years, we'll be making this comparison...
Peyton = Dan Marino.
Brady = Joe Montana.
Marino never had a dominating defense (like Brady when the Pats won the SB), nor a good running game to support him (Manning has Edgerrin, yet still hasn't won a playoff game). Marino still got to the SB w/out either, but ran up against one of the great 49er teams.
Marino's teams were completely 1 dimensional, and it wasn't until his last few years where the defense was even respectable. I realize I'm probably biased in this regard, but I think Marino doesn't get his "props" due to not winning the SB, when his teams were never had a run game or defense, both of which you need to win.
Has there ever been a 1-dimensional team that has won the SB?
