"AJ was very easy to hit for Usyk. But Mike’s small stature..." Was Tyson hard to hit for non-great Tucker? Or non-great Tillis? Or journeyman Ribalta? Or non-great Douglas? Or non-great Ruddock? Even Holmes, Tubbs and Thomas had their successes before they were bombed out. He'd be even easier to hit for Usyk, who is better than all of those fighters and Mike's defensive manoeuvres were suited to evading and countering orthodox opponents, so logically far less effective against a southpaw; a class of fighters he never trained to fight. "A non great CW who was tough" If Briedis isn't a great cruiserweight on ability then there are only two at most in the 44 year history of the division. I would say Briedis is a lot more skilled than Tyson (in terms of versatility), taller and longer than Tyson, fitter than Tyson, more mentally robust than Tyson, likely more durable than Tyson, more disciplined than Tyson and certainly far more experienced against southpaws than Tyson, having sparred Usyk years prior and beaten former top 10 Ring ranked heavyweight Perez over 12 in his previous fight. And Briedis had home advantage, whereas Tyson specialised in home and A-side advantage, which he wouldn't get in a fantasy matchup, worsening his performance relative to his irl fights. Had Spinks, Moorer and Byrd remained LHW's would anyone have picked them to beat Holmes, Holyfield or Vitali? Would they have even been great, Moorer and Byrd in particular? There are many potential reasons why cruisers (who are at less of a disadvantage obviously) don't move up, beyond Dubblechin's absurdly simplistic "They know they can't compete or they'd go for the cash and status at HW". It's totally feasible that had Briedis moved back up to heavyweight and looked to challenge (assuming he wasn't ducked chronically, as he would have been) he could have picked up a major scalp and would be seen as a significantly greater cruiserweight than he is. You didn't answer a key question of mine, which is: how many opponents did Tyson defeat who were very durable, with great engines, massive confidence and determination, elite skills (in Usyk's case probably the best ever at CW/HW), who were in our around their primes, who were not known alcohol/crack/smack abusers? While Tyson was clearly a very dangerous fighter I regard him as the most overhyped fighter in boxing history. The delusion surrounding him was so extreme that people believed he was still invincible after "fringe contender" Douglas destroyed him and he'd spent 4 years in prison and still favoured him over Holyfield after he'd been destroyed in the first fight.
