Bottom line is Tyson fought in the worst heavyweight division of all time and even then he was average.
mike tyson was an ATG and a top ten heavyweight all time.tyson doesnt get enough respect for what he did for boxing.everbody watched a tyson fight even people who didnt even watch boxing at all.he created excitment and entertained people.people gave him **** for fighting bad competition but the man fought everybody there was and crushed'em.he aint no klitchko boring guys until they just let him ko them so it will be over already.if boxing had more tysons and less wlads and mayweathers boxing would be a much better sport.
Prime Mike could beat all those guys. Of course each fight would depend on how focused he was for it. 60s Ali, juiced-up 90's Holy, and focused late-90's/2K Lewis would give him the most trouble.
