Plus i dont think the UFC will value him as much as they do in japan and offer him a poor contract.
I would love to see BJ/Aoki some day i think it will be a lot better fight than what people make it out to be, but BJ would still get the win.
ps. Why wouldnt he be allowed to wheres his rainbow pants? if that aint allowed then i wouldnt want to see him in the UfC lol.
