LONG delay by the officials who thought the ball might have been tipped on the inbounds, meaning the clock should have started when it hit the Grizzlies hand and not when it hit Bibby's hand.
THAT is not reviewable by the instant replay. They discuss it for a LONG time. The Kings are in the locker-room. Finally, the officials go over to Mike Fratello and explain that although the ball may have been tipped, the basket is good because that's the only thing they could review. Whether or not Bibby got the shot off in time; NOT whether or not the shot clock was started at the right point.
Whew....
