A lot of boxing fans are naturally negative and unwilling to give the benefit of the doubt in most cases.

Winning over boxing fans in a "majority" is a very difficult thing to do. Especially difficult with a fighter like Bradley...he's not overly slick, he doesn't have amazing power or speed, he is just an outright fighter. He has good solid skills that he uses to his advantage, he's a smart fighter, and he wins rounds. If Bradley had big time KO power people would be clamoring for him to fight Floyd, ditto if he was a really slick boxer, but he's not one of those extremes...most boxers aren't so the guys who like the sweet science AND the guys who like KO's are bummed out about Tim Bradley. He's a very solid fighter, I would say he's almost this era's Carmen Basilio. He's small, always the underdog and he doesn't care, he comes in and does his work in a blue collar style. Nothing but respect for him.
