Yea, he's a freak for sure. I was thinking the same thing about the old time rounds last night, hell even if they still went 15 I'm not sure anyone would be up for it. Thought he was toast early, like most I'm sure, but by the mid rounds it seemed like Matthysse was getting depressed over what a zombie he was in there with.
Also agree that he needs to tweak some things though, highly doubt he will but nobody can last that long fighting the way he has.
