Figures that it was Tava involved in the contact. That guy smacked a couple players in the face during the game.
I hate that I have to say or even think this, but I think there's a small (yet real) possibility that Grayson doesn't make it through the season. His reactions are instinctive, and it's VERY hard to just stop those kinds of reactions. Somebody may just get him to lash out again, and his fate won't be up to K or Duke next time.
