Which fighters between 140 and 160 would Mayweather lose to?

I don't think he does beat everyone at 160.

 

I think he has the best chance against Matt Hatton, and slim at that.

 

140-Nobody
147-Nobody
154-Lara
160-Jr.'s size would be a serious problem for Money. Also, Andy Lee(believe it or not) would give him fits...

 

Sergio (154) 60% (I'd have Sergio favored in a potential fight)
Alvarez 30-45% (He's got the pop to hurt Floyd, for sure)
Manny ~5% (Would need serious luck)

160 is too high for Floyd. He'd be in serious trouble, as would anyone who weighed 147-150 fighting people around 170.

 

Sergio Martinez at 150-160.

Felix Sturm at 160 maybe.

GGG at 160 maybe.

Pirog at 160 possibly.

There are weight classes in the sport for a reason.

A certain other fighter gets demolished by anyone at 154-160.

TS is yet another ****ing useless ******* who trolls instead of actually making good posts.

 

He would be the favorite in NV over all of them to. Can't say the same for the little guy.

 

You're ****ing ******ed, there is a reason he is ranked #1, the odds have to be stacked against him to beat him, something nobody at 154 or below (apart from maybe Martinez) can do.

 

140 lbs Beats eveyone.
147 Lbs Beats everyone.
154 lbs Lara vs Floyd 55-45 in Floyds favour. Floyd vs Alaverez 60-40 Floyd. Martinez vs Mayweather is 50-50 could go either way.
160 lbs Floyd to small for this weight and might get beat by lesser boxers because of their size advantage.

 

If Pac doubles the concentration of the juice in his syringe, I'll take him over Chavez Jr. at 160

 

I have to agree with everything you said here.
