at this point it is tough to say, both guys are strong and have good skills, and from right now i'd say that this fight is a pick'em, but i voted for kessler due to the fact that he has real good defense and good footwork not to forget that he has some power and is smart inside the ring.
only thing is, can kessler preform at his full ability in a mega bout? or will he get stage fright?
if kesslers nerves dont get the best of him i'd say he has a solid chance at beat joe. just as much as joe has a chance at beating him.............
