Interesting one. Mike was susceptible to losing to speedy "Boxer" types but to balance this out,but the Bodysnatcher could live up to his nickname by slowing El Radar up by scoring frequently in the latter phase of the bout to his opponent's body. I expect Benitez to build up a substantial points lead in the early rounds making McCallum miss and countering him but eventually he slows up and that's when Mike catches up. I go for a McCallum split decision but this could easily go the other way.
I think it’s McCallums fight to lose, not really any offence to keep him off, McCallum would work him over and while he could move his head really well the Ol Radar his body is still there.
