For one all we know most boxer have taken steroids even your god Tyson has. Thing is did Holyfeild ever fail a test in 26 years that he been fighting because since he was such a huge user pretty much says it all. As for them fighting i say Holyfield wins anytime was better fighter and had better wins in his career. I dont really think if mike came in the 90's during his prime he would of looked as good to be honest with you. The 90's had alot top fighters including the men who beat him Holyfield and Lewis during the later part was quite good as well.
