Personally, and this may sound crazy, but I think he's better off with his mediocre chin (I won't say he has a glass jaw because he doesn't, thats an exaggeration). Because he's been starched before, he knows it can happen again and therefore fights a lot smarter, working behind the jab in a more workman like manner. This was probably the case for Lennox Lewis as well. Either way Wlad is a well oiled machine of destruction in the HW division.
