He's not running, Mayweather wanted him to retake the drug test, the test which pacman had already took , so it was Mayweather who backed out of he first match, the vast majority of ringside analysts agree with that. Now Mayweather wants a 60/40 split, that's the holdup. Pacman has a damn good shot at beating Mayweather, not to mention cotto exposed Mayweathers vulnerabilities.
