from the first dev chat of 2009:
I wonder if you could lay out for us how players at each position tire. It seems to me that a catcher for instance should tire more quickly over the course of season compared to say a 1B and a DH should hold his stamina better than any position player. After several seasons of playing it seems to me like stamina is almost entirely attached to AB's and nothing else. Not very realistic. (mosley80 - All*Star - 12:44 PM)
Catchers fatigue the most, then the other position players, then DH. We're not talking a huge difference here, but it is significant over the course of a season.
