Bivol vs. Beterbiev 2. An ATG as his absolute prime fighting the best fight he will probably ever fight.
Mayweather vs Gatti - brutal and clinical Anything involving Mike Tyson from 1986-1988 Beterbiev - Gvozdyk Roy Jones vs everyone in the 1990s
Cleveland Williams got shot a couple years before so it's better to use Terrell as a example even though the Cleveland fight was a more dominant performance.
Yeah i think the quality of opponent is crucial when showcasing a performance. For me it's more impressive beating a better quality of opponent than dominating a lesser one.
I'd pick Holmes against Cooney as being his best showcase. If it weren't for sentiment Ali was a great performance, but it's too sad being a champ go out like that.
Duran in the 3rd De Jesus fight is the best fighter I've seen on film. If somebody can show me a better fighter I'd be interested.
