Credible or not, Manny has got grief in the past for not fighting prime fighters and for not fighting black american fighters. Bradley is in his prime, he's black, he's undefeated, and he's p4p ranked. I don't really know what there is not to like.
It might have been mentioned here before, but Pacquiao faced a similar type of style challenge when he fought Agapito Sanchez in 2001. Similar to Bradley, Sanchez had a reputation as a dirty fighter who was alleged to use his head and low blows to win. In their fight he hit Pacquiao with two "accidental" headbutts" and 2 low blows. Pacquiao only managed to get a draw with Sanchez before the fight was stopped.
