How is Tom Brady still so good?

[Anonymous]

I mean he's as good as he's ever been. Can he play longer than any starting Quarterback ever has?

QB's generally have longer shelf lives than other positions (such as running backs) since they take less wear-and-tear from playing the position (this is why punters and kickers also have longer shelf lives).

On top of that, he has never relied on his athleticism to be effective. He's a pocket QB so he will take less hits (usually) than other mobile QB's, such as Michael Vick. In addition, he has remained relatively healthy over the years, which has prolonged his longevity.
