First of all, the only reason Peyton Manning has better stats is because his receivers are much better than Tom Brady' receivers. Also, as you said, Tom Brady has won 3 super bowls while Peyton has won only won. Peyton manning is only good because of his receivers and Tom Brady is more reliable. This is why Tom Brady is better than Peyton Manning.
Well lets see where do I start. So last year Tom Brady had Wes Welker a great wide-receiver and Gronk who is one of the best if not the best receiving TE. Last year Peyton Manning had Eric Decker as his number 1 wide out...Eric decker is a number 2 or 3 on most teams. And last year Peyton Manning still had more yards and TD's. So don't use the wide outs as an excuse. A great QB can work with anything.
Game winning drives are always cited as an aspect of football that truly shows off the great quarterbacks. The factor that's forgotten is that in many ways, the best quarterbacks don't need to have a game winning drive.
Brady: 30 Game winning drives in 118 Wins
Manning: 45 Game winning drives in 146 Wins
2. Touchdown to interception ratio:
Brady: 2.35 TD's Per Interception
Manning: 2.06 TD's per Interception
Well you made this pretty easy on me your stats just proved my point. Manning has better stats! And has Manning had a game this year where he through 7 TD's when is the last time Brady has done that...exactly.
My stats say the opposite. to be a good quarterback, you shouldn't have to rely on game-winning drives, like manning does. Also, my second stat proves that manning throws more interceptions for every touchdown, unlike Brady who has a much better ratio. Since you don't have any points to support Peyton Manning and you are just refuting my points, this shows that you aren't saying that Manning is better than Brady in any way so I should win this debate.
