You don't think a talented freshman at another school might get 20 minutes one game, then another game only get 10 because he's struggling so they put in the experienced veteran? Other teams don't play the hot hand? Give a guy 25 minutes who normally only gets 15, because he's on fire? You sound like other teams have exact, set in stone rotations where every player plays the exact same minutes at the exact same times of the game, every game. Maybe it is like that. I don't really pay enough attention to other team's rotations to know for sure.
