Tyson by UD only. If we're talking '00-era Tua who faced Lewis, then yeah - I don't see his chin just cracking there and then (Margarito's had already been tested in many matches prior). I need to rewatch the Lewis fight, but I think he took some bombs from him and still stood at the end of 12 rounds.
However, 80s Tyson I wouldn't be so sure of. If Tua clacked him a few good ones in succession and stunned him (something that nobody prior to Buster had been able to do), I could see him being down on his ass and not getting up the 1st time. They're the same size too, so one should take that into account.
Mike Tyson.
I mean Chris Byrd defeated Tua...he wouldn't have defeated prime Tyson!
Prime Tyson wouldn't have been dominated by Lewis, nor would he have lost to Ibeabuchi.
pretty good call, i think ike would be a harder fight for a prime tyson
Tyson via Ike B. boxing clinic in a 10 rounder. But to me "prime" Tyson was after he beat down Holmes and KO'd Spinks. "prime" Tua was, what, when he KO'd Ruiz in like 19 seconds on march 15th 1996? he then lost to Ike, and he really lost to the rock so...yeah. Mike By beatdown. I'd rather ponder a test of chins between Tua and McCall
tyson by TKO.
i have no doubt in my mind that tua at his best could eat mike's best punch, but not when 4 or 5 of them in a row are landed in a 3 second time frame all night long.
you can compare it to marg vs mosley. even margarito's supernatural chin eventually cracked against someone who combined leverage, speed, power, accuracy into his shots...and most importantly, someone who would land flush consistently, over and over again.
at mike's best, he had the speed and defense to deal with tua's wide, sweeping left hook. offensively, he had the power, speed, and body attack to dispatch tua.
at tua's best, he had an insane workrate, but stylistically he was no less hittable in his prime than he was later on in his career. that lack of defense, squared-ness, and willingness to trade is gonna get the tuaman stopped, maybe even early. a straight up KTFO may not happen, but you best believe that ref is gonna jump in after all those unanswered shots.
