I think he ranks top 15. Not to harp on Fury, but I always thought Fury's movement would not be able to keep up with Holyfield's pressure.
He's only after Ali, Louis, and Holmes on my ATG heavyweight list. He had TREMENDOUS heart, a fascinating style, only man to beat Bowe (though I dispute that decision), beat a 30 year old Tyson twice, won the belt 4 times.....
A terrific fighter but, at heavy, too inconsistent for me to rate in the ATG top ten. He had a huge heart and some major wins, but seemed to always fail to put together a run with the kind of consistency I'd look for to place him higher. Top 15 for me, but with the potential to trouble any top 10 heavy on his day.
