Sure worked with Hughes.
Not sure what you're saying here, beyond making a glib "look at me" type of statement.
Are you saying that because Royce lost to Matt Hughes, that his training is invalidated? Many, many very tough guys have been beaten by Matt Hughes.
Matt Hughes has beaten and was beaten by BJ Penn (an MMA competitor whose primary art is BJJ).
I don't know or know of anyone (or any art, for that matter) that's invincible in or out of the ring. If you do, I'd love to hear about him (or her).
