Ah... Right now there is no one who can figure him out. One day there will be someone. Idk if he would be considered one of the greastest. Because honestly most of the guys in the heavyweight division are bums.
Yes, Vitali is slick. His defense is very effective. Having in mind that he fights with his hands so low, he gets only few hits per fight.
These dwarfs are not the best example if you ask me. Of course Vitali will not do that but he is slick in other way. His way.
