2002 Lennox Lewis vs 1988 Mike Tyson

[Master]

Tyson did not struggle with big fighters he beat them relatively easy it is just that you could count on one hand the moments of success they had ie Tucker right uppercut 2nd round, Bonecrusher right hand in 12th round ect

That was how good Tyson was.

You are right to point out pre 1990 that he did not struggle to beat the bigger physical fighters. But he clearly had periods of frustration against Tillis, Green, Ribalta, Smith and Tucker, as all five used their size to neutralize his awesome offence, but at a cost of very limited offence in return.

Which is where I think Lennox would fight too defensively and lose the fight albeit by decision.
