I think the 21 - 22 year old mike would of blasted Riddick out inside 4 rounds, his work rate and power would of been to much for Bowe, and he Bowe did have a habit of being a slow starter, but any Tyson after the Buster Douglas loss, would been taken out by Bowe in the later rounds (8-9) as Tyson lost the work rate, and Bowe was a very crafty fighter with good ring craft and under rated power.
