I think they should get the calls right but if they're going to review plays they need to make the players on the floor go to the opposite side of the court from their bench while the refs sort things out. They get waaay too many free timeouts while this is going on, many of them in the last minute when a team might be out of timeouts to call on their own. I also think they should NOT give a coach 30 seconds to put in a sub when a player fouls out. 10 seconds would be plenty of time, he knows who he's going to put in for the kid that fouled out before it ever happens. Once again they get a free timeout when this happens.
