Floyd wouldn't KO Khan IMO, Floyd genuinely breaks peoples hearts. But Khan has quick hands, which leads me to believe he would cause Floyd problems, but his footwork isnt great though so I think Floyd be able to time Khan, as well as make him miss and look abit stupid at times.
But I think...
I would rather see Floyd fight Khan now, Ive lost alot of interest in the Manny fight.
Floyd beats Manny easily enough on points.
Manny destroys Khan.
Khan gives Floyd troubles but ultimately loses on points.
