Who cares if he gets 500 punches to his arms? If he's covered up and they are not solid hits to the head, then who gives a rats? It's part of the sport to take hits. Who cares if he was on his back or if he curled up. What he did worked for him obviously. If another ref would of stopped like Steve would of, it would of been a bad call, it's different when you're on your back taking direct hits to your face versus when you're on your back taking hits to your arms covering your head.
