I was just watching Mosley against Collazo this afternoon and the difference in the Mosley of today and even then is night and day. Mosley still has his legs, but clearly can't pull that trigger anymore. 5 combinations in a 12 rounder from a guy like Mosley is just a shocker. Against Collazo he still looked fast and the combinations were crisp. He still has his boxing brain, but the body just doesn't respond anymore. Mayweather fought a badly faded Mosley, Pac fought a shot one.
