Spence said that he knows how to beat Mayweather.

Prime Floyd is below 147, these welterweight matchup discussions aren’t as interesting because Floyd is too old. But that aside, a southpaw with skill and sitting down on his punches, would that not create problems for the Philly shell? (Not counting Pacquiao because Spence does not fight like that, and pre-crash Spence also a fresh fighter unlike Pac). I guess what I’m saying is if you could magically shrink Spence to 140 that would be a rough fight for Floyd, and one that I’d like to see

 

Well in the immediate rematch he won much easier did he not which proved he was not lying same way Azumah Nelson beat Jeff Fenech like he was his Daddy the 2nd time after suffering from malaria in the first fight.

 

It doesn't prove it. It just means he beat him easier the second time. Could be for different reasons, maybe he just adapted better.

 

Maybe he was just better and proved it conclusively the 2nd time when he was unimpeded by injury

 

Maybe. But, again, maybe. Maybe is not proof of anything.

 

There is documentary medical proof that both Mayweather and Azumah had medical issues in the first fights against Castillo and Fenech respectively.

 

The issue is low risk high reward. He will make more money against Conor and Khabib than Spence it Crawford and evening Pacquiao now.

 

what Floyd are they talking about? Floyd Landis ?

 

Athletic but smaller southpaws like Corely and Judah both touched Floyd up a bit in the first third of their fights with Floyd. Corely actually had Floyd hurt at one point. Spence is significantly bigger than both Corely, and Judah, and his style is different as well, it is more like Castillo in that he brings immense pressure, and doesn't use his athleticism to get on his toes and box much. I could see Spence beating the best Welterweight Floyd. We saw from the Oscar fight, and the Maidana fights, that when a guy who can punch, lets his hands go, Floyd is stuck in defensive mode, and not throwing anything back. With fair judging, he lose to Spence. Spence gets credit from judges for his body attack, and Floyd doesn't have the power to keep Spence off. I could definitely see Spence winning a comfortable decision with fair judghing.
