Where does Floyd Mayweather rank as far as Shane Mosley's toughest challenges?

[Rabbit ♠]

There was a thread yesterday asking where Shane ranked as far as Mayweather's biggest challenges and I think the general consensus was that he was in the top 3. I have hime 3rd behind Chico and JLC. So, with a guy who has a resume as great as Shane Mosley, where does Mayweather Jr. fit in?

Does he crack top 3? Top 5? Mosley's resume is deep.

Even if Floyd win's,it'll still be the easiest loss of his career,real talk!!If he loses,it's just gonna be because Floyd will be on his bike throwing 1 pottshot all night,pay me 500,000 & I'll chase Floyd around a ring being pottshotted till I pass out from exhaustion!!

Floyd is in his top 3
the Forrest beatdown surprised me
Shane was supposed to be live in that fight
I see Shane more live now vs Floyd than he was with Winky
I knew Winky would roast his ass

i dont think PBF would be tough challenge (hard/physical) for Mosley, but if ever Shane beats Floyd, IMHO it will be his career BEST WIN!
