To elaborate on what I said earlier, I hate the idea of fouling out in basketball. It's stupid. In no other major sport do you see major stars have to sit out huge chunks of games, or have to play tame or soft, but you do in basketball, and when you consider the subjective nature of foul calling, that puts a ton of power in the hands of the officials. All it takes is a couple of ticky tack falls to be called on a player early in a game and all of a sudden he is sitting out for most of the rest of the first half or having to not be aggressive. It hurts the game. And, no, I don't think you should be able to rack up fouls all day, but make it to where, in college, for example, once you get your 5th foul, every time that player commits a foul, you treat it like a technical: one shot and the ball (or two shots if it was a shooting foul). That would add a lot more strategy to the game.
