The two who would give Mayweather the toughest tests would, without a doubt, have to be Paul "The Punisher" Williams and Miguel Angel Cotto. Williams' height, reach, and activity level would, without a doubt, make it impossible for Floyd to defeat him. Floyd has a better shot of winning against Cotto, but Cotto's pressure style and body attack would, without a doubt, be the stiffest physical test in Floyd's career.
