He's a hammer, but it's easy to look like a hammer against guys that you easily overmatch in a certain aspect of the game. Don't get me wrong, he deserves all the credit in the world for dominating a formidable opponent in Mitchell, but it was a mismatch on the feet. Once he was able to mostly keep it there, it was only going to go one way.
I think he's overly aggressive on the feet and I think some of the better strikers in the division would be able to exploit that, especially Volk. Curious to see it, though, for sure.
And as
@m9 said, even just getting into a title fight in the next 12 months would be pretty impressive given how stacked the division is.
