Unpopular opinion: Bivol would be a top 2 cruiserweight and a top 10 heavyweight if he moved up. Gassiev has tree feet, Bivol can win that
Prime Briedis vs Bivol is a better match up imo. Bivol loses both. Bivol also loses to Opetaia today.
Drawing the line through Zurdo I’d agree that Bivol would be a top 2 CW today. But he’d be a distant 2nd. Opetaia too big, too powerful and has the ring craft to back it up. Would Bivol beat Gassiev? Well it’s a tough one. Too close to call in my opinion.
