I mean in the NBA in the last few minutes (3 I think) refs can review any call. It gets pretty annoying because anytime there's a question on the call they have the right to go and review. I mean basketball is already annoying due to all the free throws near the end, so I think the effect is a lot worse in that sport. Either way, I hope we don't get into a routine where almost every close-ish call is being reviewed, that could add several minutes to a bunch of games which would be terrible for the sport.
