Usyk, he is more versatile than Vitali and is a bigger threat to Holmes, it would really be a fantastic fight...
For me Klitschko gives Holmes a tougher physical night. Usyk gives Holmes a tougher technical and tactical fight.
Holmes would dance rings around the robotic/stiff Vitali. Usyk is a a tricky versatile southpaw he would give Holmes plenty of problems stylistically. The answer for me is clearly Usyk.
Usyk and Holmes would have a tit for tat fight. Vitali might just win a bunch of rounds against Holmes and make him look bad.
Whilst I agree about Holmes winning against Klitschko, if Holmes decides to mix it up and get into a brawl, then we could see a lively fight.
Larry would beat both without too many problems honestly. But Usyk does better than Vitali. You should have picked Wlad instead imo
Vitalis size and awkward style alone would cause Holmes issues but instill think Holmes would be able to figure him out and pull off a decision win. Usyk obviously would be the toughest of the 2, I think that would be a great fight. 50/50 IMO.
But Norton, Snipes, Cooney, Michael Spinks, Carl Williams, Tim Witherspoon, Shavers...well, that's different.
