Which UFC fighter will be the breakout star of 2010?

Undoubtedly, DIEGO "Nightmare" Sanchez is finally ripe and due for his belt at 155lbs. He had a slim chance, with his untouchable grappling and heart at 170lbs, but he was simply too small. Now he has dropped down to his prime weight. He'll take out either Florian or Penn, or both, and get the belt. I've been following him for years now, and now it's his time.
