I'm interested by the thought of Brock in the UFC. I'm not for him, or against him really... I'm reserving my judgement until after his fight with Mir. Lesnar has definately got the physical tools to be a star, but that's far from all it takes.
The only thing I dislike, is some of the comments he has made towards other UFC fighters in some of his interviews. I'm of the opinion that it is best to be humble, Ie - make your words soft and sweet, incase you have to eat them later
