What Boxer In History Could Realistically Defeat Floyd Mayweather?

[FlatLine]

In this era alone possibly Khan, Williams and (a loaded gloves) Margarito which is why Floyd apparently avoided them all.

Margarito couldn't even hit Shane Mosely..who was no defensive genius.

Williams....nope

Khan...GTFO

[Kigali]

Prime shane mosley and maybe margerito when he was dangerous

Prime Shane had a toothache

Margarito was never dangerous...at least not in this Country.

I always thought Paul Williams would have beaten him. It's a shame we can't have time machines and change Floyd to a pure middleweight. I would have loved to have seen Carlos Monzon take his head off.

I was a fan of Williams for a while but he was one-dimensional and there's no way he ever would've beat Floyd. He was basically an AB fighter while Floyd is ABCDEF he can do everything. Yeah Paul threw a lot of punches, but he wouldn't have landed anything and would've been getting countered like crazy (See Lara fight)

I'll bet a 2008-2009 manny pacman would have given him a hard time

I disagree. Marquez handled Pacquiao in his "prime" and while JMM is great and a legend there's no doubt Floyd is steps ahead of him. He's a bigger, stronger JMM.

uhmmm, Castillo already defeated him

And Maidana

Who ELSE could have defeated him? There's a lot. Prime Chavez for one would have gave him that work, would have looked like the Meldrick Taylor fight......

The first Castillo fight was very close because Floyd was injured, once he was healthy it was an easy fight for him (Castillo won 3, maybe 4 rounds. Same thing with Maidana, Floyd had a lot of personal problems leading up to the first fight, in the 2nd fight it was easy work for him. That's 2 close fights in his ENTIRE CAREER.

I love Chavez but you saw what Whitaker did to him. Don't get me wrong a prime JCC gives him a rough night but Floyd is too complete and too smart/skilled.

Pacquiao, Margarito, Castillo, Williams

I don't like to compare different eras to eachother. Too much changes in sports. A guy from 1980 & guy fighting now are not comparable in my opinion

2004, 2008 and 2011 Pacquiao all lost or struggled mightily with Marquez. There's no year where he would've beaten Floyd. In 2009-2011 it would've been a harder fight than it ended up being, but at the end of the day he's just too way predictable. Floyd's too smart, clever for him.

Margarito was a bum without loaded gloves. Daniel Santos beat him (who?) and Mosley almost killed him so LOL at you even putting him in the same sentence as Money Mayweather. Like I stated before, Castillo gave him a close fight because he was injured. Once Floyd was 100% it was an easy, or at least straightforward win for him. Williams was one dimensional, he would've been a problem just because of his length but you saw the Lara fight, it would've been just like that but he would have been landing EVEN LESS and Floyd wouldn't have backed off and let it be close like that. He either would've easily won a decision or caught him like Martinez did. He always destroyed guys with no defense.

In this era alone possibly Khan, Williams and (a loaded gloves) Margarito which is why Floyd apparently avoided them all.

Khan? LOL. Are you kidding me or what? So he gets KO'd by Prescott, Peterson (remember him?), Garcia and Canelo but he could beat Floyd? Canelo lost 11/12 rounds to Floyd and he put Khan in the hospital. Bumgarito could've had loaded gloves, he still wouldn't have landed s"it. He was hella overrated.

[Rip Chudd]

There are a few who could in my opinion.

Pernell Whitaker
Ray Leonard
Roberto Duran
Thomas Hearns
Wilfredo Benitez

Just 5 off the top of my head

[JK1700]

The ones I would suggest are...

Sugar Ray Robinson - The length would've been hard to overcome
Thomas Hearns - I think Floyd could've won, but it would've been tough
Sugar Ray Leonard - I like Floyd in this fight but I have to admit Ray was bigger/taller and could box very well and fight inside very well just like Floyd.
Marvin Hagler - Floyd never fought at MW but if he did this would've been what I wanted to see. Hagler was a monster who would come at you with pure ferocity and could box very well too. Certainly the Hagler that fought Hearns and the fights up to that point would've been extremely hard for anyone in boxing history to beat.

I think he beats the likes of Duran and Chavez but they would gave him close fights in their primes. As for Whitaker that's a close fight too but Floyd actually trained him with when he was coming up and was a better defensive fighter and just overall a more complete boxer. Mayweather just has more to his game.

Khan would have out pointed floyd simply due to styles. It doesn't mean Khan is better than Floyd.

Not in this dimension..

Khan can't outbox Floyd. He doesn't have the ring IQ.

[N!Ck F.]

Thomas Hitman Hearns at 147. I just can't see how Floyd could beat him. He would be Floyd's kryptonite

Floyds 5'7 Hearns was 6'1...
Floyds reach is 72" Hearns 78"
Floyds never weighed more than 150-155 pounds fight night, Hearns fought at light heavyweight...2 world class boxers, one with a 6 inch reach & height advantage and weighs considerably more... Floyds that great that's how far you have to reach to say he'd lose. To a fighter who is naturally 3 weight divisions bigger then him. Pound for pound, inch for inch Floyd is litterally the greatest boxer.
