All of these reasons is why KL stayed on the bench.
Plus, I honestly believe that our ball movement is a little better when Bubu is in the game. His passes seem to happen faster and are more crisp. There have been some phenomenal "around the horn" moments this season where almost everyone briefly touched the ball that led to a big 3. And almost all of the time, Bubu was in the game.
Probably because Bubu is not thinking about shooting whereas KL does have some offensive tendencies. Bubu also doesn't have to worry about wearing himself out on D so I am sure that helps him at times. KL was just off and Fred figured out something else that worked well. When Fred isoed Will while he was the primary ball handler, OU didn't look like they knew what to do. Perfect mismatch and Will either made them pay off the dribble or found someone else who was open.
