Smack a 3 point shooters hand when he goes up and tell me what happens.Do you guys honestly not know the hand is part of the ball on a dunk attempt like that? I'm not being sarcastic.
From the NCAA rulebook:
It shall be legal for a defender to accidentally hit the hand of a ball handler when reaching to block or slap the ball when there is player control with that player’s hand in contact with the ball and when that player is:
a. A dribbler;
b. Attempting a try for field goal; or
c. Holding the ball.
Williams had control of the ball and was attempting a field goal.
