Which fighters accomplished more than their talent level would suggest? Jerry Quarry: - for a small cruiserweight with decent but not great power, the fact that he beat monstrous punchers like Shavers and Lyle. Joseph Parker - he does everything well without being exceptional at anything (except for having exceptional heart). But his wins over dangerous guys like Wilder and especially Zhang is remarkable. Carl Froch - i never thought he was especially gifted but ended up with a stellar career. Chris Byrd - a natural light heavyweight with below average power for a heavyweight. Despite his small stature, he managed to compete in a heavyweight division loaded with giants who could hit a hell of a lot harder. He was lucky to get the win vs Vitali but the win over the dangerous Tua was a masterclass. Only two guys beat the prime version of him: Wlad and Ibeabuchi. No shame in losing to either one of them.
The obvious one that comes to mind is John Ruiz. Kind of limited, but he put a nice resume together, however he had to do it. Gianfranco Rosi was a belt holder with something like 11 title defenses I believe. Can't think of a less talented belt holder with double-digit defenses. Always found that dude absolutely excruciating to watch.
Carl Froch. He had some good power, and a granite chin. But his boxing skills were always subpar for a world class fighter. The man was as tough as they come, though. Both physically and mentally. His resume is pretty damn deep. He beat some good to very good fighters. Kessler, Taylor, Glen Johnson, Dirrell, Abraham, undefeated Bute, Groves. He's just lacking that one career defining victory over a truly great fighter to put him over the top. He had his chance against Ward, but we all know how that went. Ah, I didn't see that you already mentioned him in your post. But I definitely agree with you.
John Ruiz was more of a product of King though. While Quarry defeated extremely dangerous punches like Shavers and Lyle, and Parker defeated arguably the hardest hitting southpaw in history in Zhang, Ruiz's best wins are over shot versions of Tucker, Holyfield and Golota. I can't think of a single fighter he beat as dangerous as Zhang or Shavers. I think John Ruiz was the product of King's manipulation of the system.
Byrd is an incredible overchiever. He's got wins on his ledger he should have no business in having at heavy. Hat tip Chris Byrd.
Here's a controversial nomination...... Saad - he needed superhuman feats of endurance heart in overcoming multiple challengers. It was almost his theme, get behind while taking massive amounts of punishment and come roaring back for the signature wins. Not to say the man couldn't fight and he had huge power too. Take away even a little of that heart and recuperation and some of the miracles dry up and we are looking at a different career. Vito Antuofermo would be a fair shout too before i have a further think.
Trevor Berbick did well for himself on limited skills. Bazooka Limon would be a solid shout too. Kambosos would be a good current shout.
You beat me to it to on Antofurmo. Also Mustafa Hamsho. He only lost twice in 11 years both to Hagler
Jack "Kid" Berg has always been the GOAT overachiever for me - lacked big power & was never comfortable using his height/range to box, but managed to rack up an incredible win streak by applying the same inside mauling/swarming approach to every opponent until a rematching Canzoneri finally solved the puzzle (w/ some burnout likely playing a role as well).
