He had a perfect game plan and easily won the first round he just didn't have the cardio period. Had nothing to do with his arms gassing out, he just isn't in professional MMA shape.
I usually don't think much of guys who have such significant holes in their game after 10 or 11 fights but Cody showed some real intelligence in his other fights. I think if he worked really hard on his cardio and striking he could actually turn out half decent. Obviously he has to spend a LOT of time on the bike though.
