I have no interest in watching him fight anymore. His BJJ, while very respected, is somewhat archaic by today's standards (lack of wrestling, footlocks, etc.). His salary demands would be extremely high and wouldn't be worth it from a fighting perspective, but, perhaps, it would be through marketing. If he were to get an offer, then it would have to be against someone who is also past his prime that could garner some interest. Him v Wallid Ismail would have a nice BJJ undertone (Wallid choked out Royce in the late-90's) and Wallid is a very polarizing figure. Add in the fact that he and Joe Silva have a solid business relationship and you can see the possibility increase.
