Try to reason putting Dempsey above Iron Mike. I'm a Dempsey fan but Tyson was a bigger and stronger Dempsey with more quality wins.
In terms of longevity as a champion, but I am not too positive about that ranking. You could switch em and have Mike at #8.
If we were talking all-time most entertaining fighters, I would definitely have Mike above Lennox too
Not top ten. My top list is pretty much the same as the Hall of Fame's Tracy Callis Historian International Boxing Research Organization.

I would rate Tyson around 20-25th off the top of my head.
Why do you have Liston at #10 and Mike at #20-25? What makes Liston so much better than Tyson? And seriously, you rank Liston above Lewis???
