On wednesdays(6:30-7pm),NBA.tv has a 30minute show called "Making the Call"with Ronnie Nunn,where Ronnie(retired ref.),E.Snow,and one of their hosts dissect calls,and noncalls in recent games...he usually find where a call was missed,or they got the wrong player,etc..Also,he is testing your knowledge if the refs made the correct call.Recently,he showed where Lebron shuffles(moves)his pivot foot right before he dribbles,and it doesn't get called.Sounds like he was hinting that Lebron gets away with this more times than not.Thats just one example...its a pretty eye-opening 30minute segment.
