Ezzard Charles vs Artur Beterbiev, Michael Spinks, Roy Jones Jr and Michael Moorer @175

He has the ability to go undefeated. On the other hand, any of those guys have the ability to defeat Charles. I think Spinks and Jones give him the most issues

 

Beterbiev is probably close to 200 as a light heavyweight. I know that Moorer was a 200 pound plus light heavy. Charles was better than either of them but it would be more accurate to compare them to the version of Charles that became heavyweight champion.
Charles would beat Spinks and Jones. Charles proved himself against a much better quality of opposition than Jones.

 

Charles was capable of cleaning house vs these men. Toughest would be Spinks and Jones

 

Spinks is the only problem, but I would say yes.

 

Remember, Spinks lost to Mike Tyson. Factor that into your decision making
