Someone explain this to me (Floyd/Hatton weight issue)

[Trainer Monkey]

I dont think anyone is saying he would have beaten Mayweather,but he would have had a much better shot if he had been tighter and in better shape is more what both of us are saying.
I still think Floyd would end up being too slick for Hatton's style,but he would have had a better shot at it lighter

Spot on Bro .. simple as that

So you are saying he would have won more rounds? Or maybe see the final bell? Or maybe he had more of a punchers chance? If you are not saying he would win, then maybe I missed the original point of this topic as written by beanflicker:

Apart from Joe Cortez, the biggest excuse for his loss was the weight they fought at. Both guys are the same height, Ricky started his career (and stayed) at 140, Floyd starts his career at 130. Ricky is known as the bigger fighter, a guy who balloons up between fights and kills himself to make weight.

So how would the fight have been any different if both men had to weight in at 140? People say Ricky isn't a WW. True, but neither is Mayweather. Mayweather is just a guy fighting in weight classes he has no business in because he's going where the money is.

So how would have 140 made the fight different? You'd think weighting at 147 would benefit Ricky more, because he's the guy who kills himself making weight. Would extra hours spent in the sauna cutting weight make Ricky better? Would making 140 be to PBF's detriment? Why? He's in shape 24/7, 365 and never has an issue making weight.

More of a punchers chance,and his activity rate would have been better,Ricky's activity rate seems to slow when he gets heavier,Floyd is not a fighter you can afford that against,because say what you wish about Floyd,his activity rate is top notch.
Every time Ive seen Ricky carrying a few extra pounds he looks sluggish,and not at all fast off the mark.
Against a guy with an S-y chin maybe it wouldnt have made an ounce of difference,but that isnt PBF
