Stevens stayed in there and got the win, but he was lucky! Lucky he finally got the punch he wanted and lucky the referee jumped in so fast.
In my opinion, Johnson gave Stevens a straight up mauling for 9.75 rounds before that punch. Too bad, Johnson lost concentration for a second.
I don't want to sound like I was against Stevens in this fight, I just hate to see victory snatched from the fingers of any fighter who tried so hard and had the fight in the bag. Hell, he would have been better off just covering up and letting Stevens have the last round.
