Depends on which Mercer shows up. Mercer at his best UD in a relatively slow paced fight. Mercer not at his best (which is very much a possibility) loses a decision. If they fought 20 times I'd think all 20 end in decision barring an injury.
Good. Its weird how some fighters get overrated because of one or two fans have developed an undue fixation.....surely no one could look past McCall's 'sparring partner' syndrome despite the odd fluke win.
