The dude is a hell of a talent, good to see him signed, he may struggle in the UFC though.
I don't think he'll struggle too much to be honest. He's already faced some of the best in the world, hell he's been all over the world.
He said himself a couple of years ago that he wanted to go to UFC but he wanted to do it at the right time when he was ready for it. UFC had offered him a contract in 2005 & 2006 but he refused.
Surely he must be a lock to fight at UFC 105? I really hope so.
