Why did Mayweather fans say their boy was the best but didnt have to fight the best?

[Saloth Sar]

Kostya = Showtime Fighter
Mayweather = Hbo Fighter
Kostya Hurt for 2 Years and had to rematch Mitchell when he came back. and then took another lay off. and then fought hatton and Retired.

So there was no way Floyd could fight Kostya within any kind of rational thinking being involve.
Floyd could have fought Cotto at 140. But Cotto said he wasnt ready.

there is no way Floyd could have fought anyone good enough to bet im,he'd run for the hills!!!!
