text: do you think the referees in basketball are bad at calling fouls? and that there should be camera to challenge the foul to be fair........just like in football the coach can challenge the play why not in basketball? yes, but the key is to be consistent.   if they called everything no games would ever be finished.   a replay system would only add to the delays and confusion.  at the speed the players are moving at, and all of their various body parts moving at incredible speed, it is almost impossible to accurately call everything.  especially when one considers the sheer number of things they're expected to watch for.
