Ketchel Greb Walker Steele (great boxer, but obvious Tough nut too) Thil McAvoy Zale LaMotta Cerdan Fullmer Giardello Monzon Briscoe Carter Hagler Benn Froch GGG Boxers and Stylist need not apply... L-HWs like Fitz and Co need not apply, only Main Career MWs.. Pair them anyway you want and add overlooked or Forgotten Tough Guy Middleweights, i.e Dillon, Gibbons, Houck or other more recent men, Leahy and so on. You get the idea, True Middles Only and Only the FIGHTERS, Hardmen, Tough guys. who are your finalists and winner.
Giardello had the heart of a lion and throughout the fifties fought many many battles and wars, but along the way, he acquired many ring smarts and became a boxing wizard...using those smarts successfully against Tiger and Carter....but he was indeed a fighter at heart and should be considered here.
