This has been discussed a lot over the years but I think Tom Brady's play this year should bring it back into legit discussion. I always hear that Peyton is the best QB in the NFL and that Tom is 1.B - but I see it completely different and this season is another reason why.
Tom is performing surgery on the best defenses in the NFL. Without Randy Moss. Who really only gave Brady one season before he stopped being Moss half the time. Peyton has always had receivers and always played in a dome. Brady has had 4 Superbowl appearances with only one of those where he had great receivers to help him, and it was a juggernaut.
Now he is surrounded by youth and a bunch of hard working but not elite in talent counterparts. Look at the results. He is obliterating the best defenses in the league.
It didn't take long after Brady got his knee mashed up and everyone was putting Peyton back on the top of the list and people were calling Brady a system QB etc etc.. Also there were those that said he would never be the same ala Carson Palmer. Yet after a little over a year he looks just like 2007 Tom Brady. All while Peyton has looked frustrated by his lack of talent to play with because of injuries.
I think Peyton is one of the greatest, but I think Tom is 1.A while Peyton is 1.B -- I even think Tom has done enough to be put in the discussion with Joe Montana.
Another note is this is a young team. A team with a ton of draft picks and very good young talent on an emerging defense. Belichick blew it all up and started most of it over so he could do it all over again. He thought long term and I think its going to pay off big. IMO this team is about to be the team to beat for the next 5 years in the AFC.
