Firstly, I will not mention Fitz, Langford, Ketchel and Choyski because they're just too old. Here's who I think the hardest middleweight Punchers. 1. Julian Jackson 2. Gerald McClellan 3. Thomas Hearns 4. John Mugabi 5. Eugene Hart 6. David Lemiux 7. Merqui Sosa 8. GGG 9. Nigel Benn 10. Bennie Briscoe 11. Rodrigo Valdez 12. Sugar Ray Robinson 13. Eduardo Lausse 14. Florentino Fernandez 15. Carlos Monzon 16. Marvin Hagler 17. Rubin Carter 18. Juan Roldan 19. Rocky Graziano 20. Iran Barkley
Archie Moore is best known, of course, as a height heavyweight (and to a lesser degree heavyweight) but he campaigned for a good while at 160 and he knocked out a goodly percentage of his opposition there (although he didn’t face as many top guys at middle). Worth a mention.
They're just too old for me to actually judge them. Besides there's barely any footage Fitz and Langford. Yes they can punch but I just wanna rank the guys that I could see. No hard feelings
