Cleverly - 5 defences Khan - 5 defences Woods -4 defences Maccirinelli - 4 defences Witter - 2 defences All couldn't hack it at world title level for long all will go down as about the same type of level. I'd say Clinton Woods has the best resume out of those followed by Maccirinelli.
Carl Froch 7 defences at super middleweight Ricky Burns 4 defences at Lightweight and 3 super featherweight David Haye 1 defence at cruiser weight 2 heavy weight
Surley,Lennon Lewis, Johnny Nelson , Scott Harrisson ,Froch ,Ricky Burns ,Ricky Hatton, Neseem Hamed all come into play
Haye with 3 title defenses - impressive - actually it can we really count a fight with fraudley a title defense
Carl Froch has won 10 world title fights all against top opposition back to back. 4 time world champ legend Joe Calzaghe won 22 world title fights, made 21 defences. won all the major belts at super middle. real legend. Ricky Burns is 8-1-1 on world title fights. 2 weight world champion David Haye only won 5 world title fights but that is different cause he was undisputed unified cruiserweight champ with 3 world titles then moved up and became a 2 weight world champ. Maccirinelli/Cleverly/Khan could only win 4 or 5 world title fights in the same division. And Cleverly and Khan are the worst cause they fought weak opposition. Khan had a razor thin win against Maidana, a cuts win over the Domestic level Mccloskey, A low blow against the past it Judah, a mismatch against the awful Salita.. etc hardly impressive. Maccirinelli actually beat two very good big punching former world champions fighters .. Wayne Braithwaite and Marcelo Dominguez... not fighters with high profiles but if you'd seen them you'd know they were top world class fighters.. two solid wins Enzo doesn't get enough credit for. Mark Hobson was no muppet either.
