Leave it to Carroll to get away with that.
...not so much in the NFL.
Yeah, it was illegal...but they couldn't see it on the field.
It was still fun to watch.
EDIT: Having watched it again, I've having deja vu: MJ's winning shot in game 6, 1998 versus the Jazz, and whether he knocked down Bryon Russell before making that shot. Many internet commenters claimed (and I tend to agree) that given the direction Russell was already moving and the degree of force that might be imputed to Jordan's hand movement, it's likely Russell fell because he was trying to reverse direction, not because Jordan knocked him down.
Here, Wagner does place his hands on the players to his right and left, but is he actually getting leverage in the physics 101 sense? He started his leap before he placed his hands, and it doesn't look like his trajectory changed after placing his hands. But not wanting to get all Zapruder-y about it, I'll accept the overnight consensus.
