He was trying to pull his leg to make it appear as if it were an illegal moving screen.
He hooked him so hard, they both tumbled to the court - that's an easy way for someone to end up with a groin pull (injury that has sidelined Isaiah Livers for weeks now).
Coupled with tripping Wieskamp from behind on a 3, and sticking his feet until Jordan Murphy rebounding (and add in numerous other clips of the same behavior) and you have a picture of a kid who is trying to injure others for his team's advantage.
He needs to go. Yesterday. No other BT players should be exposed to intentional injury on the court. Davison blinks wrong, and he needs to get lifted in his next game, if the BT refuses to act on the evidence already available.
Any player injured by Davison should sue the Big Ten, Wisconsin and Davison's family for everything they can get. The kid is psychotic and as dirty as they come. Just because he's white and likes to recite Bible verses isn't a defense.
