lol all of that is just silly.
BJ didn't take chances because he was very obviously tired as shit early in the fight. He was also very outmatched, you saw the size difference between those two, right? And why the fuck would anyone be scared to KO someone in the UFC, that could make you a shit load of money. I don't think BJ has ever been KO'd.
forgot to mention how BJ got pretty hurt from body shots early as well. Dude was hurt and tired, but still can't be KO'd
