Two things. I'm pretty sure Berto stopped Bradley in the amateurs and I'd probably favor him now over Bradley. Although Bradley made the foray into welterweight waters with a win over Abregu, I believe staying at 140 makes more sense for now because there are enough lucrative matches there. He has Marquez at 140, which would be a good clash of styles and if he emerged victorious could lead to a Pacquiao showdown, and he has Khan at 140 in a unification match. Both are potentially bigger money fights than Berto and less risky.
