Is Thurman Mayweather's biggest challenge?

[Boxing lives]

Floyd Mayweather proved he could get the job done against an excuse minded Pacman the last time out. Obviously you can't blame Pac for trying to position himself for a rematch with an injury excuse to roll in the dough again. But thats not until next year and Floyd will just beat him again anyway. So I ask what is the biggest challenge for Mayweather at welterweight? GGG can't make that weight so he's out. Khan stylistically present one heck of a challenge. But people will say he didn't truly have a full camp and had to squeeze it in after ramadan. Besides that, the Mayweather that came out and took the fight to Pacman in the first 2 rounds probably puts Khan to the canvas. So I'm looking at Keith Thurman. The guy is big, underratedly well rounded and a boxer/puncher. He has the size and knows how to use it. He is in his physical prime and just pulled off a win against Guerrero (who beats most of the top WWs right now including Khan). Him and Brook both look excellent but Thurman's leg is not suspect from taking a machete to it. Disagree? Who is a bigger challenge?

This is the fight I want tbh..I think it makes sense and would be a great fight..

[El-blanco]

Totally agree.

Thurman is the likely air once floyd and pacman are gone. The present vs the future. No disrespect to Brook who also is right up there.

I think Thurman would be a little harder than Brook for Mayweather to beat. Both Brook and Thurman are very good welterweights and deserve a fight with Mayweather more than big mouth Khan. Khan is Mayweather's next fight in my opinion as long as he looks ok against Algieri.

If the machete attack did any permanent damage to Brook it would have shown up even in a short fight. His footwork was as good as ever and I think leg damage is not an issue.

A moderately decent athlete with respectable pop. That is Keith Thurman.

The current crop of American 'talent' gives me AIDS.

style wise i'm not sure how much of a challenge thurman presents. Mayweather needs to be roughed up and beaten up in a dirty fight like maidana did. Thurman has very good power, but hes gonna box and use that power from the outside which will allow floyd to stick and move and box circles

[John Locke]

I don't think so. Thurman hasn't got the right style to beat Floyd, the fight would a chess match, Thurman is at his best against aggressive fighters.

There's nothing wrong with Brook's leg btw, it's completely healed.

Miguel Cotto.

Lead hand dominant, commitment to his jab, strong body puncher, can cut the ring off, strong in the clinch and has the intangibles: toughness, experience, etc.

Yeah I know he only won 4 rounds but it is what it is. He has the tools to make the toughest fight.
