KC is one of my favorite BYU players of all-time and I agree that he is energetic, but I don't think KC has good energy on defense. Watching the game today was a broken record of KC going over the screen, trying to backtap the ball after his guy blows by him thanks to going over the screen, and then slowly moseying over to a spot for defensive rebound. When that wasn't happening, he was losing his zone/man when watching the ball, looking to get in place for those rebounds. KC is so rebound hungry that he sacrifices playing sound defense.

Just my opinion and observation.
