How was that a sucker punch!?!?!? The guy was done fighting, that's why he walked away. Kimbo did a bitch move and punched the guy in the side of the head WHILE HE WAS WALKING AWAY! If you honestly think Kimbo could do some quick training and hop into MMA fight you are retarded. Do you have any clue how much training it requires to even be decent in MMA? I can tell by the way Kimbo fights in the videos that I've seen that he isn't shit for a fighter, he's just a big guy with some power. Put him in MMA with his weight class and watch him get KO'ed quick
