What was comical and sad is that when the Broncos reaped the benefits of a superior defense is when Peyton lost his physical ability to play the game. Just imagine MVP Manning and the SB Bronco's defense together...wouldve been legendary.
There's no right or wrong in this debate. Some only see SBs and some only see regular season stats. But my only point for Peyton over Brady is that Peyton was a bigger asset. Cassel did well with the Patriots when he was injured, I think to a 10 win season. Then players like Jimmy G, Brissette, and Mallet looked like franchise players but it was all a front for the ingenuity of Bill.
