Vitali isn't his brother. He has no hook, he's slower (although his reflexes are better), he arm-punches, and he relies on winning exchanges rather than attrition clinching. His footwork isn't up to Wlad's standards, either. And he's cut and injury prone. Vitali has advantages as well, and was an excellent fighter, but those advantages aren't the ones that usually troubled Ali. Foreman? Yes. Ali? No, wrong style for that fight.
