you have a point but Bradleys never ducked anyone, went to England to get the title, has fought the best competition he could so I don't think anyone thinks he's afraid of Khan...
I think he's just trying to get the most money he can, the fight will happen!

then you have Khan... got the title by getting the champion to come to his home country, fought the opponents who pose no threat to his chin and are mostly smaller guys coming up(Maidana the only exception). Talks crap none stop and really makes it easy for people to hate him. So shoe on the other foot yeah Khan would get abuse, mainly because he's a cnut
