1. Benny Leonard 2. Ray Leonard 3. Pernell Whitaker 4. Ray Robinson 5. Ezzard Charles 6. Joe Louis This group is the best of the best in my opinion. Louis would beat anyone of comparable size. I think the more modern tall heavyweight who uses their size to control the distance.
P4P i'm not sure i'd have him above fighters such as Billy Conn, James Toney or Evander Holyfield. Although he ranks higher at HW, i dont think he's above Marciano in a p4p sense either
I don't see how James Toney could be ranked above Joe Louis. Holyfield and Conn are a bit of a stretch too.
