Won't be a popular opinion, but tyson was too strong for him. He had real good skills, but i don't think his style would translate well against modern hw
I don't think Louis has a problem in any era, vs any size. But I don't think he beats Tyson. Mike starts too fast and has too much power IMO. He'd go in, find Louis and get him out of there. If he doesn't, Louis probably stops him late.
While he beats some big guys, they were rather clumsy for the most part. I'm not sure a 205 pounds offensive guy who wasnt a speed daemon could cut it against modern big hw, no matter how skilled he is. But then again, fat toney did pretty well at hw, so who knows
Louis was perhaps the best rematch fighter ever so maybe if he got a rematch against Tyson, he could figure something out to trouble Mike. Be as it may, Mike quick and easy.
Louis would slaughter AJ as well. I think Lewis and Fury are the only two big guys I'd give a good chance of beating Louis. Bowe, Wlad and Vitali have like, a 30% chance or so. Louis stops the three of them IMO.
