It may be a good fight for 20 seconds after that they both will gas out. Ill go with Rahman for the upset.
Rahman will win if he has 30% left. Mormeck doesn't belong at hw. Then hopefully he'll get a shot at Haye, so Haye's team can try to hype that match up more than the Harrison fight already has been. But seriously, maybe Rahman can fight Holyfield after for the interm geriatric wba super heavyweight (super championship) title.
