Jon "Bones" Jones's combination of MT, Greco, and fearlessness make him one of the best prospects in MMA right now. Jones has a fight coming up against human blanket "Irish" Jake O'Brien at UFC 100.
Bones' future is very bright. Hopefully he doesn't get fed to the lions too soon and they develop him like they should any young and up and coming fighter.
Going from fighting Stephan Bonnar to Jake O'Brien is a step down, so they probably don't want to rush him, either.
