I honestly don't think people would give very much credit to Mayweather based on the chronological oppertunities he would have had to face Mosley up until Shane beat Margarito. I mean he lost to Cotto in his biggest WW fight in recent years up until that point so the arguement would be why wouldn't Mayweather face Cotto, but not only was Floyd expecting to face Oscar again, but he fought Hatton like a month after the Mosley-Cotto fight and subsequently retired. I honestly don't think he would have had that much trouble with Miguel and that he wasn't run out of the division. Then Margarito beat Cotto(the first thing that made margarito a marginally valid opponent for Floyd), but he was still retired and once again there would have been a million excuses for why Floyd beat Tony as easy as he would have. Then Shane, thankfully, beat the crap out of TOny and I honestly think he and Pacquiao have made themselves out to be true threats on paper to Mayweather. I think they are the type of fighters people think can truly test Floyd, but there wasn't anyone truly like that when Mayweather was orginally at WW.

Also for somebody who was gone for 16 or 18 months between Hatton and JMM, I don't think 1-2 inches in height and 4 pounds in weight really signify a large difference in "Size". Honestly it was Mayweather's speed and skill that made him so dominant over a guy who's style matched up very poorly with Floyd's. But Mayweather still pissed me off by not trying to make weight.
