To be honest he does have a beautiful right hand, but it's not so much as a devastating right that will end a fight, but that pull right hand counter is something to behold and not many can do. Perfectly timed.
Box him I think. Forget about brawling him. He is the king in the center of the ring. Pick the right moments to let your hands go. Oh, and overhand rights like the few Clottey threw.
This is the interesting part about a Floyd-emmanuel fight. They both excel in the center of the ring.
