Lets address the whole Tyson V Ali thing, Ali wins hands down, period. Remember Ali had an incredible jaw so he could take Tyson's punches, just watch Holyfield v Tyson 1 to see how to dismantle Tyson...clinical!!
Tyson was at his best under trainer Kevin Rooney. In 1987-88, Ali would not have lasted more than a few rounds against Tyson. No fancy footwork or rope-a-dope would have done Ali any good. IMO, Tyson would have punched right through all that and knocked him straight to the canvas. In the post Rooney years he went downhill and by the time he fought Holyfield he was already washed up. Ali could have easily beaten a 1990's Tyson. Watch the Tyson vs Holmes or vs Spinks in '88.
