Only Champions who never defended a World title are elligible, if they defended one in a different weight class they are ineligible. Brian Castaño and Jessie Vargas defended their WBA (regular) titles but Erislandy Lara and Danny Garcia held the (Super) title*
I actually think Victor Ortiz could've been an excellent champ if he had the right mindset and more heart.
Roberto Duran vs Sugar Ray Leonard. Duran won the Title on June 20, 1980 and he defended @ The Super Dome in NOLA ,USA on Nov. 25th. We know the rest. At the time he was 73-1 and the P4P Champ and the Fighter of the 1970's by the Associated Press if memory serves, but my memory is suspect @ this point so I may have my Associations in a Twist regarding Writers Organizations. He was the Man @ the time. Outcome: Leonard TKO 8. A lot of people lost money on that one. Some had it right. Duran broke my Heart as I was 15 and it taught me a lesson about Hero's and False Idols. I still love Duran. He did eventually "redeem" himself.
I assume you must mean successful defenses because a lot of these guys had defenses. Of those on your list, Diaz would be the best but he did have a successful defense. Sadam Ali is absolutely the worst.
