I see Sherk winning and I see B.J. moving to 155 to challenge him. He should do this to re-establish his dominance, he needs to, after coming off back-to-back losses. If B.J. does, he'll become the second fighter to win titles in two different ufc weight classes. That is, if he comes in with improved cardio. A damn shame his cardio gave out against Hughes, he was schooling him until then. If B.J. doesn't come down to 155, then I see Spencer Fisher being Sherk's biggest challenge.
