Football has natural breaks in the action that have always made it practical. Basketball does not with any consistency. About the only thing you could consistently overrule during the breaks which you CAN count on (the quarters) would be toe on the line 3 pointers etc. (and even that not in the final quarter when it would change strategy). Otherwise you either have to repeatedly stop play -- a disaster to the flow of the game -- or wait to change something later that would have had a definite impact on the game in realtime. No good way to do it.
