What does this have to do with how long he plays? Also, his numbers went up like everyone else, but nobody else has the numbers he does. Its all reletive. If you want to argue that stats are higher, I agree, but as far as playing. Its not true. It would be like if Brady was the only one who's numbers went up and you said well the only reason is the era while nobody elses numbers went up.
Numbers have also went up becuase they pass way more now than they did. If you watch games from the 80's itw as 3 yards and a cloud of dust, the run game was important, its not as much now. Yes the game changed in that way, which puts the QB even more at risk. By the way 2007 was 14 years ago, not 10.
