the value of fouls

Fouls can totally change a game, of course. The difference between not shooting FTs and shooting the double bonus is huge. And when a coach has to take out a key player because of foul trouble it can change the course of the game. Every game strategy has its points, but the Princeton offense (or similar perimeter-oriented strageties) does not draw fouls nearly as frequently as some others. There is a good reason why post players and slashers shoot the most free throws.
