Not meaning to try and sound like a know-it-all, buddy. In the end, you may be right.
I'm just pointing out the reasoning for my opinion. Only time will tell the answer, but I do think (right or wrong) that TFB should be in a better position than those who he'll be compared to in the same age bracket, which is around 40-41 or so.
I don't believe that guys like Marino, Favre, Warner were constantly pushing themselves as workout warriors, or winning their team's "parking lot award" for the best workouts in the offseason, etc. I think they relied on their pure talent, and rode that until it wore out. I would think that Brady has the opportunity to best their efforts by an additional year or two.
