i dont see tyson bullying tua, tua may land the heavier shot, and tyson could go down. tyson is probably quicker, but tua is bigger and more powerful, it could go either way.
My inital thought is that Tyson, being much faster and better defensively, would blitz Tua. get him out in a couple rounds; sure, Tua has a solid chin, but he'd get hit with a gang of big punches. After that, in the third and fourth the advantage would shift towards Tua and this would be his chance to get tyson. In the 5th and 6th Tyson would rev up again. After that it would be a wrestling match as both fought on adrenaline and physical advantages, not brains. Most likely, tyson would beat him in 2 or 3.
Tyson KO/TKO within 4. Tyson would eat Tuas hook for breafast, but He prob wouldnt get hit with one cleanly. Tyson was more powerful, quicker, better chin, better left hook imo, and a nice jab to boot. This is prime Mike so body shots are gonna be involved
His first pro fight the guy was alot shorter and against Buster Mathis jr Tyson had the height advantage i believe
Tyson would eat Tua. Tua trying to load off to one side would fall perfect prey to Tyson's ability to attack at radical angles. As long as Mike DIDN'T pass left, he would barely be touched all night, and he'd have ample room and time to punch as Dave reset. If Mike passed right and ate a big left, he might get sparked, but I just don't see that happen. Tyson UD, and I think he REALLY messes Tua up. I don't pick a stoppage because Dave would be on the defensive constantly, and did a great job protecting a very strong jaw, and Tua never panics in there.
