I would say Wlad and Tyson might be a toss up for me now because they both have something in common, which is getting beat by people they should of crushed. I will say this though at least Wald made improvements and went on to win. Tyson just got his ass beat and went out sitting on the canvas not even wanting to get up. I still rate Tyson on the lower part of the top ten though behind people like Holyfeild and Lennox and of course the greatest. As for Wald i would not rank him till he is retired its always a better idea i think.
