I agree Tom Brady has accomplished more in his career, but I personally think Peyton Manning is a better QB to have for a play. No doubt about it, Brady has won more and accomplished more, but if you had one play where you needed the job done, I would go with manning, who is better in a situation.
My best example is fourth quarter comebacks. Peyton Manning has 31 4th quarter comeback wins, tied with Montana, and Manning has played two seasons less than Montana. One of them I remeber most destinctively is the Colts-Pats game last year. Manning was down by 17 points in the 4th quarter, and with 5 minutes left down by 14. Tom Brady had a chance to put the game away when they were up by 7 on a 4th and 1 play. Tom Brady threw it to Welker, who didn't get the yardage. Manning came back and scored with a mere 17 seconds left. How can you say Manning wasn't a better QB in that situation?
Also, look at what Peyton Manning has. He has had to deal with ENTIRELY new offensive lines, entirely new recievers, and changes in the entire offense (with a running back that isn't necessarily the top in th NFL). Are Garcon, Collie, and Wayne good recievers? Definitely! But if they had say... Donovan McNabb throwing to them would they be very good? Probably not. And with the offensive line. Either the Colts have the Godly power to get a monster offensive line every year, or manning is really good. Look at the sacks. I don't remember seeing Peyton Manning get sacked in forever... He ALWAYS gets rid of it. Tom Brady? I seem to remember a particular super bowl where he was taken down with 30 seconds and a 3 point deficit, and more common week-to-week cases.
Tom Brady could be a better QB overall, but things like the 4th quarter comeback stats make Manning a bit better. Plus, Manning has 4 MVP awards ;)
I agree with what you said, Tom Brady is for wins (except when undefeated against wild card teams in the super bowl ;) ), and Manning is for numbers.
Oh! And interestingly enough, I found an ESPN article compairing the two. Read it here.
I found it quite interesting :)
