Usually I’m not much of an NFL guy, but this came across my twitter timeline:
SportsCenter calls it crazy, but is it? Quarterback is the most cerebral position on the field. It stands to reason that the more a player plays, the wiser he gets. A quarterback may not be able to have quite as much zip on the ball as he did when he was in his early twenties, but the difference wouldn’t be that big.
Also, be wary of assuming correlation implies causation. There are many other variables at play here including coaches and teammates.
