If you haven't already, check out this video from Mayo's last game.
With about a minute left in the game, he tapped the ball away for a steal, then got a pass and was open on the break... where he decided to toss the ball off the backboard, slam it down, and then toss the ball into the stands. Not like a flip, a full out throw into the stands. This coming right after the story of his recruitment.
I'm definitely happy that UCLA never went after this guy recruiting.
