Joe Montana lost a playoff game 49-3 in his prime, when you're playing a great team this can happen.
Peyton is definitely a great QB; but I couldn't help but notice you only listed wins, which, of course, only tells part of the story... here's the rest of it:
In the SEC he won 1 SEC title, and lost to UF all 4 years. He said the only reason he came back for his senior season was to beat UF, and Wuerffel had graduated, so he thought he had a pretty good shot at the elusive win... he lost to the new guy, too, Doug Johnson.
Yes, he's won 11 playoff games... and lost 12.
Yes, he's won a Super Bowl... and lost 2.
Again, he's a great QB, but he also benefits from an NFL that emphasizes passing more than any time in history...there are probably a dozen better QB's that would have inflated passing numbers as well as multiple awards and records had they played in this era.
I thought it was kind of ironic that he again lost to a (former) UF defensive coordinator, Dan Quinn.
