Someone needs to explain to me why Floyd doesn't deserve to be mentioned with ATGs

[Hunter]

I said before the fight that Shane was past it and it would be a lopsided Mayweather decision. Floyd isn't mentioned w/ ATG's because
A)Ducked too much top opposition
B)Safety first fighting Style
C)He hasn't achieved as much as Pacquiao
D)The one which I believe is most important. We don't know what we got till it's gone.

Who has Mayweather ducked?

Whether he ducked opposition is subjective but it doesnt always seem that Floyd's top objective is fighting the best. He didnt fight Hatton at 140 and didnt seem in any kind of rush to fight Margarito or Cotto back a few years ago when the fans demanded those fights. Now with the demands for rigorous blood testing, Floyd, in some peoples minds will appear as though he is afraid of Pac. Personally I believe Floyd would dominate Pac and should just take the dam fight.
