Im going to go against the grain and pick Reggie by upset in a close decision. I think his speed would trouble Mike and while Reggie isnt nearly as good as Mike on the inside he can hold his own. His movement and speed would give Mike alot of problems. Add that he was durable and had a good chin and didnt fade down the stretch and I think he takes a razor close decision that could go either way
I picked McCallum by SD so I agree with the close fight part.In a close fight, judges often side with the aggressor being in this case Mc Callum. However there is a chance that Reggie would get the nod depending on the judges. You are right that Mike is not going to be super effective chasing Reggie around.
