You know who would've knocked out Ali is that Allan Green. Ali was prone to left hooks landing on him.
We can only say for certain if Ali hadn't have ducked really tall Ukranians while fighting random short American guys like Frazier and Shavers and whoever throughout his career. :conf
Still not as bad as Frazier though. Don't even get me started on Joe ****ing lizard man Frazier again.
These things are of course extremely hypothetical, but I think Ali may just have to be at his sharpest to beat him. He wouldn't really be able to exploit Wlad's vulnerabilities against power and agreession, and I think Wlad's jab and right would give him problems. I may actually give Wlad a better chance than just about anybody else. Very hypothetical, of course.
I see this as a similar fight to Ali vs Bugner only Vitali doesn't have Bugner's mobility. Ali would pot shot his way to a clear decision using his superior hand and foot speed. Vitaly is big and strong and takes a good shot so I don't think Ali ko's him but gives him a boxing lesson all night long. Vitaly certainly isn't knocking Ali out so outboxing him is his only chance and let's face it fellas...that aint happening. Ali unanimous decision.
