Greatest Title Run

some average opposition in there though. :yep

 

Joe Calzaghe. undefeated SMW, 22 world title fights, WBO WBC WBA IBF Ring titles, beat 2 undefeated world champs in winning the titles.

Dariusz Michalczewski 24 successful LHW title fights WBO WBA IBF titles should have also been WBC due to beating Rocchigiani who was wrongly stripped of his WBC title and Ring title due to his unification win over V Hill, only The Ring removed credibility by handing the title to Jones when it was Dariusz who beat the MAN.

Sven Ottke undefeated SMW, 22 world title fights WBA IBF titles

other possible names -
Zsolt Erdei successful in 12 LHW title fights, undefeated former WBO champ
Naseem Hamed successful in 16 FW title fights WBO WBC IBF and beat the WBA champ who had been stripped

 

Carlos Monzon. His reign beats Hagler's.

Joe Louis also had a great reign.

 

Danny 'Little Red' Lopez.
Only [8] successful defenses, but every damn one of them was exciting.
Not a dog in the bunch.
You knew he was going lose, but when,,,,,,,,,,

 

Mike Spinks deserves an honorable mention. He had a nice light heavyweight run, especially if you include the wins over Marvin Johnson and Lopez.

 

1. Joe Louis
2. Benny Leonard
