Good for Wiuff. I always liked him. He was never that durable, but he is so darn chinny now (thanks to his three-months-consecutively 45-pound weight cuts to light-heavyweight in Bellator, which was interestingly the highpoint of his career) that he can't take anything his opponents give him, and there's not much you can really do about that at heavyweight, and it really belies the talents he has. I'd even be willing to say that Wiuff has one of the best top-games in the entire heavyweight division. He'll never really get to show it or use it since his takedown game/style isn't strong enough to just be able to take guys down right away, and his striking isn't good enough to prevent him from getting KO'd by a good striker, but it's still very good.
Sims isn't exactly a very high-level win now, but it's as great a victory as he can get at this point.
Sims is only 38, too. Who knows, maybe he can make a comeback. 38's young in the heavyweight division... fairly. That's probably not gonna happen, though.
