Well, the pros: He can bang, has brutal ground and pound, plus he seemed very strong physically. The cons: Quite vulnerable, careless when attempting takedowns, not so polished striking skills (unlike Brandon Vera). Nevertheless, the kid showed heart. Grove had him in submissions twice and was on the verge of getting choked yet he hung tough. And when he got his man on the ground, it was just a matter of time. Correct me if I'm wrong but I see a vintage Mark Coleman in there. His power and exciting style will get him a lot of high-profile fights. However, the middleweights is a minefield full of talent: Palhares, Franklin, Belfort, Marquart, Sonnen, Rosholt, Quarry, Rivera. His glaring flaw can turn into a fatal liability especially when he recklessly charges in. However, it seems like he will stop anyone who he can take down on the ground.
There would be a lot more hype around this guy if he hadn't been KO'd by Hamill in his debut. He's great to watch though, and he can still become a contender if he wins a few more fights.
He's striking has gotten better but still need a lot of work. Defense and bjj also need to improve. Middleweight is loaded with talent so he needs a lot of work if he wants to get a shot at the title.
His GnP is some of the best since Fedor. The man hits a ton even w/o leverage. But lets be honest here, he aint going far.
