I don't know who wins this one. I'm not overly impressed by either of them, I see a good competitive scrap though. Neither of them is going down easy, especially Matthysse. Argentine guys are tough as nails.
i just personally know how the man trains and pushes himself. Conditioning has never been nor never will be a problem with him. Brandon is a gym rat and an over achiever.
And to answer the question I dont find anything impressive about Matthyse I think he's getting seriously overrated for just barely doing enough to beat a way pasted it Judah. Even with the weight advantage I think Rios out punches him.
