exercise: If one of Utah's backup Centers did this to Mika, how would you react? Would you view it as an awesome way to send a message, or would you think that it was a cheap shot? What about a Utah State backup who thought it would be fun to put a shoulder into Nick Emery when he wasn't looking? How would you feel if Karnowski pulled the same stunt on Kafusi tonight?
My guess is that if any of those situations happened, you'd be incensed (and rightfully so).
There's nothing trollish about calling Kafusi's play what it was - a dirty, unsportsmanlike cheap shot.
