and you could tell where he got hit by his feet flying out from under him and his head snapping back as he was hit?

The only way to knock him off his feet that way is a sharp hit to the head. The blockers arms were to low for that to be true. Watch the kid fly off his feet and you can tell he was earholed.

The point is it doesn't matter where his helmet hit the defender, just that he lead with his head, no doubt that is what happened.
