While it is true that Manning has always had a better recieving core, but Brady has had a 100X better defense, arguably the best coach ever and without question the best coach in the league right now, they have always had great special teams play.
Manning can only control so much, he was scoring 40 points a game most of his career because his D would give up 35.
The Patiots have had the best overall team, but imo Manning is a better QB. Sure Brady has more rings, but both careers arent over and Brady has had better overall teams, better coaching, etc. Brady can think Bilicheat for those rings because they would have won them if they had nearly any other QB back there, well except for Grossman.
I mean we could go deeper into the whole deal but Viniatieri imo was the MVP of those teams. Without his clutch foot they wouldnt have won them.
