Lewis wins hands up.

Lewis size mixed with the Kronk Style is one of the worst thing ever for Mike. I could see Lewis frustrating him with his piston like jab and grabbing him when Tyson would be able to close the distance,doing so for 4-5 rounds (as Tyson was known to spend a lot of gaz and to fade a bit passed the fifth) and then mixing up the jab with even more power shots. It would be a very interesting match up and the HW division being the HW, one punch can make all the difference, sure Tyson could technically have"some chance" but I really believe that LEwis would win this one in a dominating fashion, especially because not only did he have a better technique and a better size but was much smarter and able to adapt in the ring than Tyson.
