I am not one to blast the refs, because as Aunt Bea says, I've never read the rule book. BUT in the last two weeks, I have seen more refs overturn calls than I had ever noticed before. Do we need instant replay? 99% of the time, the first call is the correct one. As silly as it may sound, is there a senior ref? One that can call the shots over the other one or two? The guard was already on the sidelines with the ball in his hand when another ref overturned the out of bounds call. It occurred at a very critical time in the game.
