Since then, Hughes has looked surprisingly good while B.J. has lost twice (albeit to the same guy), and suddenly you have Hughes-Penn III. And a lot of people are picking Hughes.
These are two guys who have been in UFC for more than half of the organization's existence. Penn lost twice to Frankie Edgar, who's like Hughes and sort of a similarly stocky, wrestling-based fighter.
I still have a hard time seeing Penn lose, but Hughes' body type makes him so hard to beat on the ground just because he's so ridiculously arm-strong stocky. This could be a really interesting fight that you'd expect mostly to be on the ground.
It'll be interesting to see Tyson Griffin. It shows you how fast these careers change: Griffin is basically fighting for contract, vying for his UFC life. Not that long ago, Griffin was not quite a name-lister but a pretty credible fighter.
