Why do people think a pure boxer like Mayweather, can't lose?

None cause he looks for guys past there primes

when jose luis castillo wins at least 12 rounds against you, youre pretty much very beatable

it's not that floyd can't lose-he has lost in the amateurs----he just won't lose to pacquiao and martinez---it's just his skill level and mindset in the ring---he is leagues ahead of everybody else for what i've seen--it's a testament to his skill and dedication to his craft, that's all--he is human--he can lose-lol

15 world champions he's beaten. That's more than Pacroid. Dude has proved himself. He just did it so easily that alot of people failed to recognise it. Pacroid has absolutley no chance of beating Mayweather. Floyd is just too skilled. If the fight ever happens it will be a mismatch because of the skills. But it will never happen because Pacquiao will never agree to full, random, olympic style drug testing with no cut-off. Without the PED's he has no chance, and his team know it.

Please.

Dude would have lost if he would have went up in weight against Mark Johnson or Michael Carbajal.

Dude just hid in one division for the majority of his career.

Him hiding in the 105 division is no different than Sven Otte hiding in Germany for his entire career.

Mayweather would lose to not only Pacquiao and Martinez, he would also get ktfo by Khan
