Cal uses it, a lot of coaches use it.
I think it is stupid, at least to be a hard-fast rule for coaches to use every time, every situation, every player.
Why?
What do you want from your players? You want to get the most out of them while they are on the court. For your better players that means you want to maximize their time (minutes) on the court. You see it happen a handful of times a season, a key guy gets 2 fouls in the first 4 minutes, and because his coach goes by that rule, the player can play at most 24 minutes that game. But doing that means he doesn't get a breather in the 2nd half, which also might not maximize his play. So maybe he's down to 22 minutes max.
Are the last 4 minutes of the game more important than say 4 minutes in the middle? Some say yes, I say it depends, so no.
NO one wants to foul out. A guy gets 2 early fouls, he will be more selective, more careful less aggressive going forward. Now if the player takes that too far, then defensively he could become a liability, so the coach needs to consider that. How much better is this player with 2 fouls (or 3 or 4) than his replacement.
But I'd rather get 28 minutes from PJ but he foul out with 3 minutes to go, than 22 minutes from PJ and he finish the game with 3 or 4 fouls.
Now there may be exceptions. Say the guy is your primary ballhandler and best FT shooter, then maybe you really want him at the end of the game (where he will be getting fouled) more than the middle.
But when a guy gets that 2nd first half foul, or 3rd foul with more than 10min to go, it probably is a good idea to sit him for a minute, just to remind him he has foul trouble, so don't commit any silly fouls. And if the team is playing well without him, no need to rush him back (we saw that midway in the 2nd half on Saturday then Travis sat for a bit). But if things start to slip, I would put my better players back in.
