Toss up, though slight edge to Bivol only because Beterbiev is getting old now. But perfect matchup of styles. Bivol is a better boxer, but Beterbiev is no slouch or just a puncher/fighter. He had a decorated amateur background.
Will Beterbiev or Bivol even get sanctioned next time. The Canelo fight was already made when the war kicked off.
Depends on when it happens. Right now, it's a pick'em fight. The more time passes, the better for Bivol.
