who should mayweather fight next??

[Wayne]

I went with Mosley because that's the fight I most want to see, but the Pacquiao/ Cotto winner is a close second

I just feel Mosley brings the greater challenge!

But you know that won't happen. Just ask yourself which would be the bigger payday and go down from there. The Mosley-Cotto winner will give him the most money and he won't have a problem waiting until then. Then he'll consider a Mosley if he's still relevant.
