Though the more appropriate question is would Haye ever get into the ring with Tyson? Assuming he did, Tyson KO 2
This is about as mythical as you can get. Haye would NEVER step foot in a ring with Mike. Well, unless Mike came outta retirement tomorrow. Assuming the fight did get signed though, they'd have to drag Haye to the ring as he'd be literally pissing himself with fear. Assuming he makes it to the opening bell without fainting or jumping out the ring, Mike ends it within 2.
It wouldn't work. Soon as Mike lands anything half way decent, Haye would be out for several minutes.
Haye shits himself, literally, en route to the ring and tries to run away for as long as he can. He lasts as long as Bruno did, and is decapatated in the second round. T-shirts of the decaptation are worn by funeral goers afterwards as an ironic gesture. MTF
Haye lasts longer than Bruno did. Bruno was a kentucky fried bum. Slow as molasses, predictable, no movement; head or body. He was basically a robot. Haye is mobile, fluid, fast, awkward. It would have taken Tyson at least 7 rounds to get to him.
^^^^^I think Haye would have been so intimidated that it wouldn't allow him to make that kind of an effort. The first punch Tyson would PARTIALLY land would have him shitting his pants.
