How exactly can he hide at 154? That's absolutely no advantage for him anyway. Packy and Floyd weigh damn near the exact same on fight night. 8-4 rounds is a clear win. Floyd fought a better version of Cotto anyway. Pac would never fight Cotto at Cotto's comfortable weight.
Cotto fought gamely with an excellent game plan by Diaz. Mayweather was just better. Cotto will be back im sure. I hope Mayweather goes on to something better but you never know.
Hide at 154?? Floyd isn't at his best at 154. If he was to hide it would be at 147,much more competition at 154 for him
