cotto or khan. i feel thurman is too green. but cotto is locked up supposedly for canelo showdown. khan has ramadan.
Khan has ramadan and why should Floyd give Khan a pay day. Using Khans line of argument - he wont fight Kell Brook because Brook disrespected him and wants a pay day. No Khan does not deserve the fight - he needs to fight Brook first.
Khan or Brook I think are the only interesting fights left. He beats either handily, but Khan might give him problems for a few rounds.
Although i don't think Thurman is ready i think he may have the best shot at hurting Mayweather. Khan can't fight because of ramadan. Brook could be interesting. No one else comes close.
