George Blanda played until he was 48 years old.

Blanda was just a kicker at the end. The question is Brady's willingness to play at 80% when the drop-off comes, making him still well above average but not best in league. Kinda like where Favre was in the end.

Brady has the advantage of a strong offensive line. So he takes fewer hits than the average quarterback. I think he will pass on this race and not run.
