His power isn't all that impressive, he's defensively quite porous, his reflexes not sharp enough, he's a violent KO waiting to happen.
Seems a lot better when the opponent is coming forward and he's able to counterpunch. He gets a lot more sloppy/one dimensional when the opponent sits back and he has to come forward.
Doesn't look impressive, sloppy hands, plodding foot work with and a poor record. Just seems like every other up and coming heavy weight now.
