Wladimir has come to grow as a fighter. He knows his limitations well now and so he won't be so easy to knockout. He is very cautious because he knows he can not bang. His chin is not glass but its not heavyweight standard. In the weak heavyweight division its not really fair to Wlad that he can not be really tested. And why is everyone talking about Wlad like he the dominant heavyweight champ? Vitali is the man of the division. Does anyone really think Wlad is better Now comparing Vitali to the heavyweight past greats is the real warranted discussion!
