Which of Floyd's opponents, had they fought 5 times, could beat him at least once?

[texasboi15]

If Mayweather fought one of his former opponents 5 times, which fighter, if any, do you think could get him at least once?

All its boxing anything can happen.

maybe JLC gets a gift decision at one point but doubt it

[SlySlickSmooth]

Castillo, MAYBE, and eventually De La Hoya would of gotten a win in.

Put Floyd in with a peak 147 Oscar or a prime Shane...they'd be problematic to say the least...

Mosley and De la Hoya, I see younger version of those two at their best weight in a fight of 5 beating Mayweather at least once.

[DeadLikeMe]

Sugar Shot Oldsley put Floyd on queer street...most of you know where my allegiances lie, but Shane was a great champion who often doesn't get the credit he deserves.

no brainer...Henry Bruseles

The questions was "which of Floyd's opponents" had they fought 5 times, could beat him at least once? Not who or if they were prime would beat him.
