I don't think Tyson would have ever beaten Holyfield the style matchup was awful for Tyson. Tyson needed to be able to move on the inside and Evander's huge noggin kept crashing in on him. I think James Toney would have been a bad matchup for Tyson as well...not that their careers at heavyweight ever intersected.

Tyson maybe 2 out of 10 times could have gotten to Lennox Lewis when Lennox was younger, but once Lennox had Manny in his corner he was hard to catch unless he took his eye off the ball in training.

Under Rooney's training Tyson did move his hands better, he did jab more, he did move his head better, but again that style does have its weak points. If the fighter isn't letting his hands go he's a sitting duck, if the fighter is being tied up or leaned on he'll lose energy, if the fighter isn't moving his head he won't be able to get in range....look at Liston vs Patterson 1 & 2. Patterson was trained by Cus and Patterson got steamrolled twice.
