Holyfield should be very high on the list. Someone said they didn´t rate him highly because of who almost beat him. That´s exactly the point! Holyfield was the ultimate warrior..."almost beat" translates to Holyfield digging deep and coming back to win. "Almost" shouldn´t be a factor, as long as Holyfield won. That´s why Marciano is the hero he is...Because of hardfought wins. Just look at the record. Fought Bowe 3 times, Moorer twice, Tyson twice, Stewart twice, Foreman, Holmes, Mercer, Dokes, Ruiz 3 times (everyone scoffs at Ruiz but Ruiz has made a career out of beating people he should not be able to beat, ugly or not). Holyfield knocked down Bowe who had never been down, Tyson who had only been down once, Mercer who had never been down. Holyfield on his best night (probably the first Tyson fight) was no joke and would probably be even money with the prime Tyson (Tyson was a bit past it when they fought, but not a lot)
