While I have him at top 10 based on his accomplishments, he's basically a 155 lbs Jake Shields with mediocore wrestling. He's an absolute wizard on the ground, I think he submits 75% of the LW and FW division. But the problem is those divisions are so wrestler heavy, he might not even get the chance to show off his skillset.
If he wants to be taken seriously as a UFC contender, he HAS GOT to improve his striking. And I don't mean improve it good enough to get the fiht to the ground, I mean improve it so that he causes problems on the feet. Fighters with glaring holes, whether hyped or not, don't fare very well in the UFC, let alone "Dominate". That is an absolute FACT.
