The fighters with most potential decision changing fights on their resume

Sven Ottke comes to mind. He retired undefeated but had multiple close decision wins in his home country of Germany. He easily could have four or five losses on his record.

On the other hand, two of his countrymen Axel Schulz and Felix Sturm were robbed in title fights that took place in the US against Foreman and De La Hoya.

 

You said earlier the Hearns win was tainted but now it doesn't have an "*".

The ringside poll right after the Hagler bout favored SRL and tho a close bout and Hagler certainly wasn't "jobbed".

The Hearns draw gives Leonard little to zero legitimacy as virtually everyone knows Hearns won and Ray conceded that. It's a good fight between two past prime greats.

Hagler's win over Duran is not better than Leonards. Duran had beaten Ray in a grueling bout and he came straight back to right the ship. The first fight was Duran's greatest performance. It was 3 years later when Duran fought Hagler as well as two divisions higher for the former lightweight. Hagler was 3-1 favorite. He was fully expected to win.

 

I can't think of any more of a biased opinion as this one. Or silly, or both.
It's so easy to look at a glass as half empty as long as it suits one's agenda.
But what about half full? What if I say to you Leonard defeated four of the best fighters of that era while all of them were in their primes or close to it.
You say Hearns was completely out-boxing Leonard the 1st fight( As if this was some type of disgrace, because how many fighters from welter to cruiser out boxed Hearns? ) but what your blinders refuse to see is Leonard, like atg's do found away to win, Leonard did what was thought to be impossible at the time, stand in front of Hearns, and out fight him. Doing that was thought to be strategic suicide prior to that fight.
The Brawl in Montreal was an excellent performance by Duran . But that fight demonstrated one thing about Leonard, he wasn't afraid to walk into the lions den and fight. It was a strategic mistake on his part, but he proved more on that one night than Mayweather Jr proved his entire career. I became a fan of his on that night.
2nd fight like it or not, Duran quit. Leonard punked the bully, Duran did something inconceivable in a boxing ring. Though the fight was close ( And him quitting made that a bigger disgrace) he turned his back and walked away. To save face from losing to a hated enemy? Probably.
The Hagler fight was supposed to be a slaughter for Leonard. A lot of fans including me thought he could get killed. Everyone says Hagler was past his prime. But so was Leonard, and at least Hagler was active and focused on his profession. Leonard was out partying, drinking, and doing nose candy( his own admission) Leonard was out for 5yrs.
Who should've won this fight? Shouldn't the fight have been disastrous for Leonard? Embarrassing?
Maybe that very fact DID sway the judges a little. I thought Leonard won. But history shows close fights usually go to the champ. Hagler and his team took Leonard lightly. It happens, everyone wants a feel good story. That was a feel good story to all but Leonard's passionate haters.
And as usual, the Benitez fight is an afterthought to folks with an agenda. It's one of the better fights in history between two prime, ATG's at the top of their games. The skills BOTH men showed that night hasn't been duplicated since.
Your entitled to your opinion. But in my opinion your very wrong and very bias.
