If Castillo was still in his prime, I would have loved to see him fight Mayweather in a third match-up at 147lbs how do you guys think this wouldve played out especially considering the fact that Mayweather developed into a gifted technician I got Floyd by UD or TKO DEBATE!
Mayweather would crush Castillo and every non-Euro-level athlete in and around his division, including Pacquaio. I think his stiffest opposition comes from European athletes at 147 like Jan Zavek, Selcuk Aydin, and Viacheslav Senchenko.
