Haye in his prime has great headmovement and is very elusive. However he wouldn't be able to keep up with the pace Iron mike sets and if he somehow doesn't get lit in the first few rounds he will be done by round 5-6. If Derek Chisora can pressure Haye enought to make him gasp for air then I wonder what Iron Mike would have done.
That is a very good point, but I don't think Haye would exchange with him like with Chisora. Chisora does not pose as much of a punching threat as Tyson. I think Haye would use different tactics and try and fight him from the outside.
Are you insane? PRIME Tyson would absolutely obliterate Haye inside 2 rounds. The HW division for the past 10 years or so has been a complete joke. None of those guys would be competitive with the 90s HWs, outside Klit just because of their size, but even those guys are horrible. Technically awful, clumsy and slow. Guys like prime Evander, Tyson, Razor Ruddock, Bowe were on another level completely than these 2000s HWs. Just go watch Evander vs Bowe, than go watch Haye vs Chisora. The crisp combinations, the way they move their feet, box and brawl, speed, technically near perfect execution of every punch. Then the sloppy Haye/Chisora bar brawl/hugging, flat foot, slow, clumsy, technically very flawed.
