Filthy KO, it was like playing Fight Night where you continue to beat up the guy that's already out against the ropes.
Yeah to me it looks like Bigfoot is enjoying himself. He is probably taking his anger out from the previous 2 rounds of being somewhat mocked. It also looks like he was more then willing to continue beating Overeems head in when Overeems lifeless body collapsed. If Herb Dean didnt jump in id hate to see what would have happened.
