Amir Khan would beat Floyd Mayweather jr.
There is no doubt in my mind that if Amir Khan fought mayweather he would be victorious.
He has the style to beat him. Khan's speed & his jab would present huge problems for Floyd. Old man De La Hoya's jab was giving mayweather problems.
Oscar beat Floyd too.
Imagine what Khan would do? Mayweather never picks an opponent with a jab.
Khan would defeat mayweather I'm certain of it.
Amir khan > Gayweather.
