Haven't seen many of his fights... Seems a bit undisciplined, but if you can knock out Mark Hunt who needs discipline.
He is just a wild brawler. It's a waist to put him up against a decent grappler because they can take him down with ease. But if you want to give him the guys that like to "put on a show" then he is always game and has a chance to beat anyone if they keep it standing. He doesn't have the best chin though. But it's always fireworks on the feet and someone is going to sleep as long as it stays standing.
