Would this be the play by any chance?
YouTube - Keith Thompson hit on Matt Cline, UM vs. App St. 12/12/09
Already posted on the Refstripes forum and discussed somewhat there, but in the context of being a Personal Foul and possible taunting.
My view?
1) Incomplete pass.
2) Personal Foul under Rule 9-1-3-a which states:- No player shall initiate contact and target an opponent with the crown (top) of the helmet. When in question it is a foul.
3) A further 15 yds for taunting under Rule 9-2-1-a-1-g which states:- Specifically prohibited acts include punching one's own chest or crossing one's arms in front of the chest while standing over a prone player.
But certainly, if someone doesn't teach that young man about not lowering his helmet when he goes in for the tackle, he could end up in a wheelchair.
