Larry Holmes George Foreman Muhammad Ali Evander Holyfield Joe Frazier Honourable mentions to Ken Norton, Joe Louis, and Riddick Bowe (prime)
It changes over the years. Today, it's Tyson Fury, Deontay Wilder, Lennox Lewis ... at one time Golota was on the list, so was Bowe, Tyson, Foreman, Ali, Liston, Patterson, Louis ... in the 80s I liked Coetzee and Cooney a lot, Leon Spinks, Thomas ... I was a big Weaver fan for a while ... I didn't like Holmes while he was champ but liked him after he lost the title ... I always rooted for Michael Spinks. I liked Norton and Shavers in the late 70s. Bruno and Morrison in the 90s. It's a fluid list, in other words. (LOL) Can't keep watching the same fights and fighters over and over.
