Montell Griffin? Not a good choice for the thread, IMO. He was actually quite a skilled boxer, an excellent spoiler type for Jones. Aside from the first Jones fight (which was very close through 7 rounds, as Montell made Roy look worse than he ever had before), he also fought Toney in two close, competitive bouts, though the decisions are disputed.
Guys like Douglas, Baldomir, even Al McCoy won their titles with legit wins over well-respected fighters. They shouldn't be the first picks for this list IMO. Guys like Luis Santana (DQ over Norris) and Julio Cesar Green (gift over Joppy) would be my first picks.
Here's some of the Champions with the worse career records: Eddie Connolly was 25-21-17 Steve (Kid) Sullivan was 30-26-4 Mike Ballerino was 43-37-17 Johnny Jadick was 85-57-8 Saoul Mamby was 45-33-6 Wallace (Bud) Smith was 31-23-6 Joey Archibald was 61-42-5 Ricky Parkey was 22-20 Nico Thomas was 29-23 Manny Melchor was 38-35-6 JB Williamson was 26-16 Leon Spinks was 26-17-3. Tommy (Spider) Kelly was 5-9-4 by boxrec and 24-11-4 (1 NC) by Ring Record Book. Frankie Neil was 29-17-5 Monte Attell was 27-29-21 by boxrec and 46-38-21 (1 NC) by Ring Record Book. Harold Dade was 43-30-6 Eleoncio Mercedes was 14-12-2 Fritzie Zivic had the most losses with 65 Johnny Dundee lost 62 bouts
Guys like Zivic, Dundee, Mamby, etc. might have the worst records, but they're far from the worst champions.
People put a lot of emphasis on the fact Moore had so little experience when he faced Duran. But I dont see the point in padding up a record to make it look prettier...He had more experience then probably most of the prospects floating around with twice as many fights on their ledger. He had a stellar Amateur career...Prevented from going to the Olympics only by Don Curry it seems (even though they would end up boycotting it)..Being a Golden gloves champ in New York is more impressive then winning the national title in my country Id say. And this kid did it 4 times in a row. He had been champ for 18 months and had traveled to fight in Japan, Italy and South Africa since he turned pro. Beating the very talented Kalule certainly warrants praise. He probably wasnt ready for Duran..with his style he probably would have never been..But he is a good fighter, who wasnt near as green as people seem to think.
For my money the weakest of all the heavyweight champions was Paddy Ryan. I think that he would barely have been a second rater in either the previous era or the subsequent era. When he was matched with John L Sullivan he was lucky not to get himself killed.
I think there's just too many contenders if we're talking alphabet champs of the past 25 years or so, from Shinji Takehara to Six Heads Lewis, Michael Bennt to Glenn Catley. If undisputed world champs are just to be considered Backus and Leon Spinks were good choices.
