I doubt that Timmy is afraid of anybody. His advisors, on the other hand, might not want to risk his 0 until it's absolutely necessary. Bradley really isn't a viable opponent for Pacman. The best he can probably do is fight Khan. That would be his best payday, he just has to realize it's the best he can do. If he loses his title, then his marketability goes down even more. He needs to get active and realize he is not as popular as he thinks he is.
Bob Arum is the Don King of Lightweights lol.... Bob prob promised Bradley a fight with Manny... its ironic 2 c people choosing fights for big paydays... they obv dnt love the sport... just work up the ladder.
