We had "Unavenged losses that hurt careers" so it's only logical we flip it!!! I'll start the ball rolling - Joe Louis vs Max Schmeling - Max was on the down a bit and Joe on the up from when they had previously fought i think. This devastating win is probably Joe's signature and it well and truly transcended boxing at the time. Lennox Lewis vs Hasim Rahman - It was important Lewis came straight back and show Rahman did not beat the best of him and he did so in devastating fashion. One could only imagine the haters if the rivalry stopped at one fight. Sugar Ray Leonard vs Roberto Duran - Extremely important win for Leonard's psyche and confidence and sure doesn't hurt his resume. Muhammad Ali vs Joe Frazier - Ali's two wins after the initial loss are a big plus on his resume. He lost the initial battle but he won the overall war. A trilogy that enhances both warriors legacies. Roberto Duran vs Esteban DeJesus - One of the great trilogies where Duran emphatically righted the early wrong. Again a series that enhanced both combatants. SRR vs Turpin/LaMotta/Fullmer/Basilio - Not much need be said. Yes Fullmer came back again at him but when he still had something to offer Robinson came up with one of the greatest one punch ko's of all time. I'll stop there and not hog any more. I'm sure some would like to put their own spin on guys like Patterson, Norris (lolz), Hagler and Charles to name just a few. No doubt there will be some brilliant more obscure mentions too.
Maybe not a official win as such , but Hearns draw with Leonard and putting him down twice. It gave Hearns a shot in the arm and proved he could come back from been hurt. It definitely helped Tommy.
Tarver, after Jones I, could have easily gone down as just a footnote in another man's career, his "Dave Tiberi" so to speak, the guy Roy squeaked past after having unexpected troubles with him (with some calling it a robbery and others just a close shave) - if they never fought a rematch, and especially if Jones retired then and there, it would have altered both their legacies significantly. Jones would be immortal, and Tarver would be almost completely unknown, occasionally namechecked as "that last guy Roy beat". As it happens, Tarver made the most of the rematch. It put him in the headlines, in heavy rotation on ESPN's highlight reel, and into the catch phrase hall of fame - and set up arguably every future opportunity he ever had (including the rubber match, where he got to double-dip on victories over Jones). He raked in a cool $13 million in just the immediate 3-year period after Jones I: $2 in the rematch, $2.25 in Johnson I (a bit less in the rematch, somewhere between a million and two), $4+ in Jones III, and $3.5 versus Hopkins. Plus another eleven fights after that, with significantly lesser payouts (but even the draw with Cunningham in 2015 netted him $1.1 million) but all income he could arguably trace back to one rematch.
Do you think B-Hop really needed to avenge the loss after that much distance and having already done his thing with the lengthy MW title reign and jumping up to LHW to beat Tarver (and then Winky, and Pavlik)...? I mean, granted, Calzaghe fought basically the same version of Jones and the consensus does seem to be that without Jones (and Hopkins) on his resume, the pearly gates of Canastota don't open for Joe...but that's different. He needed their names to get himself off the bubble, as his career was viewed as, while not devoid of some other shiny wins (Eubank, Lacy, Kessler), full of too many long grey expanses of Blah. Hopkins didn't, I suspect, need to settle a seventeen year old score. He just kinda wanted to, because testosterone. (going to prison just pumps guys so full of ma-cheese-mo, don't you think?)
Hagler drew with Vito he didn`t lose. The fight where Ray defeated Duran was one of the most significant fights in history, the brawl in Montreal was huge, Leonard was trying to become a legend by adding to his great win vs Benitez, if he never got revenge on Duran it would have tainted his entire career despite the Hearns fight, Duran was a legend and at welter was still some force to beat him like that proved so much about RAy he just had to beat him.
Nobody gave Hopkins any credit for beating a washed up Jones and Hopkins hadn`t peak yet in their first fight which was boring.
Vito isn't in the conversation - Watts and Monroe are. The guys he lost to and avenged. Agree it was important Ray beat Duran, absolutely.
Listen Earsy lad, we'll have none of your sass on here. This is, like, a serious interwebbyforum, ya know? No jokes, quips, jokeyquips or none of that ****. Serious webbyforum. SERIOUS! Right, Harada decisioning Medel in the rematch was an important one for him. It established the blueprint for him to beat Jofre. I thought Kingpetch lost both rematches against Harada and Ebihara clearly despite getting some home cooking in his favour. But he acquitted himself very well in both fights after being iced by Ebihara in a round and beaten half to death by Harada first time(s) around. Pac coming back to topple the fading Morales twice got him back on the right track. Gonzalez twice decisioning Carbajal in their trilogy after being knocked out, and by boxing on the back foot when his default setting was to attack.
