Like most big guys the second he's put on his back he didn't have a clue what to do. Probably spends all his time in the gym on top doesn't know how to defend or sweep. Goddamn am I sick and tired of some of these heavyweights, their level of all round skill is just terrible.
I mean the guy just shelled up, didn't throw any upkicks, didn't try to get to his knees or roll, no submission attempts off his back...just rubbish.
