Who is the bigger threat to Mayweathers "0"

[.PrettyBoy32.]

Why is Floyd's "0" so important to you guys? Berto is undefeated too, why not talk about his biggest threat?

Because Berto will eventually lose lets face it, He had trouble with an old Callazo,
Floyd is on top of his game and it don't look like anyone out there has what it takes to beat,
Therefore I made a poll as to see which of these two fighters do people thing have the best chance of beating him?
Fairly Obvious I thought mate

It's important to people because Floyd puts a lot of emphasis on him being undefeated & '0'.

Noone Floyd Mayweathers size or smaller can beat him in this day and age. Sergio's size will allow him to bully Floyd, unless he tries to box, in which he get's beaten 10-2.

[KILLA RIGHT]

money would have a tough time with pwill and sergio. Manny imo would be a easy fight

[Kobe B Bryant]

any top guy who is not a featherweight or 40 yrs. old.

Both will be a threat to his 0. Flyod will find a way to get an advantaged on both guys or no fight.
