money wise, khan can fight FMJ, pick up a fat paycheck, then go on to fight brook and pick up another one, if he fights brook and loses he's not going to get a mayweather fight style wise I'd like see fmj vs khan, I think khan may win a jab battle with his speed + height advantage which will make the fight interesting if khan gets ahead in the earlier rounds. I disagree with a lot of Eubanks comments but the below statement may well be true. "He'll be winning on points over Mayweather if he uses jabs and feints, like Thomas Hearns was over Sugar Ray Leonard, and it's then a matter of whether Floyd can dig deep and prove himself a great fighter by overcoming adversity to get a knockout or draw"
Brook would beat Khan, styles - Brook'll time Khan and knock him out with a power counter. Khan wins every minute of every round against pillow paws Mayweather.
Just for the record: Eubank Sr. might not be the smartest guy on the planet. But definitely the best dressed!
