...By the way, I think the call was blown on two levels.  Owusu hung onto the ball until his forearm hit the ground.  The ground caused the fumble--except it can't.  It should not have been a turnover at all.  If he had possession, then it should have been a completed pass...

Yes, and if you claim that he didn't have control of the ball (because his arm was limp even though the ball was still tucked until his elbow it) - Its because he was knocked unconscious by a helmet blow to the head.
