Who would win this fantasy match-up between the best 2 heavyweights of all time? I think Haye's far superior movement and speed would ensure victory though Ali might cause difficulity at times.
I think Ali has the superior handspeed, chin, ring generalship, and is much more tested at the weight. I don't think it would be close to tell you the truth.
If Haye was not able to hurt Valuev for 12 rounds then Ali at wheelchair would have his moments as well :deal Its not like Haye would never corner him or stunned his tires a few times but I doubt that he have enough speed to reach his armrest, tear out the upholstery and make the fight really ugly and uncomfortable for Ali. The only chance I see for Haye is to shut off the oxygen tank early and let the old champion quit on his chair after second round.
