Well how could he possibly not improve? A couple of years ago he was literally more likely to knock himself out than anybody worth a damn. I just don't get why anyone is behind the guy, he is a talentless oaf who cant even punch. That said it is, sadly, possible he will pick up a belt some day as long as people want to watch him. Even now I think there are probably a good dozen guys outside of the Klitschkos who'd whip him though.
