Seen enough 'non trained' fights to know that's not how it looks. Look at it again, watch it closely. So Tank hits him (we have the added Hollywood punch sound effect) and when Cheston comes back up Tank throws a weaker than weak punch. In the headlock, it's a half assed punch, not even trying. Cheston lays Tank down on his back ...doesn't throw him, almost cradles him to the ground.....before the punches fly. Then watch how many of the punches actually make contact.....several look like they make contact with his chest, .....
Most fights end up with pushing shoving, wild haymakers, ..... Could the fight be real? Sure, I just don't see it though.
