It's time to settle this debate once and for all. Who wins this match between two great HWs? 15 rounds.
I actually could see Vitali getting cut against Ali. Ali was a master at causing cuts with his jab. Of course, he never faced a 6'7 boxer with the skills of Vitali. If Ali could get to him enough he could cause a fight ending cut, otherwise it would be a boring fight that would end in Vitali winning on points due to his height, reach, skills, chin, and mastery of distance.
And you're ******ed to think frazier has a chance, you know the natural cruiser with a 35% KO ratio on 215lbs+ opponents.
