Let's look at this era in more detail. Byrd and Ruiz were champions for crying out loud. Even James Toney a big fat MW did very well as HW. In fact I thought he won the first Peter fight. So do people think Ali would not do well against this bunch? In this era only Holyfield and Lennox Lewis where really good fighters. Let's face facts. Wlad has never been tested in his career. Could he win a very hard fight when he need to dig down deep to pull out a win? I doubt it. Ali did, so did Holyfield and Lewis. Heart chin and ring smarts are major factors in boxing. I don't see anyone today that has that. Anyone who is willing to walk through fire in order to win. I see good but not great.
