I wouldn't totally blame KJ's cardio, he's ALWAYS too patient with guys. He spends the whole fight setting shit up with those body shots and then when he lands the big shot he doesn't swarm. I don't think it's a cardio thing, it's more like he just decides it was enough or something. Its weird, he's got a ruthless streak in him but he just seems uninterested so often. Look at his face when he threw that big right, he was trying to kill George. Then just back to patient boxer guy instantly. He's weird.
