30. If you can't tell that his knee is on the ground I can't help you. Anyways it actually doesn't matter, because the rule is if the intent of the quarterback is to down the ball, which it clearly was, no fumble can occur. And why did the officials signal second down? Why did they blow the whistle after he went down? Why didn't Arizona state immediately jump on the ball? Look at the replay, the dline started lining up for the next play before one of their guys jumped on the ball. Hell even the guys on the pac12 network said it was a disgrace.
