Not a Pac hater, and I never was a Floyd fan until recent years, but I must say bias is always present when comparing Floyd and Manny. Pac has a better public persona (I think) but I know one thing, he did not and probably could not reach this level of stardom without claiming Floyd is scared of him. They whole mystic of Pacman comes from Floyd haters wanting to believe Pac will do Floyd the same way he does the mediocore fighters he fights.
Also, while i feel Pac lost a decision he should have won against Bradley, judging by Bradleys bad feet AND still outboxing Pac in the championship rounds, makes me think Pac is just afraid to face Tim again. Looking back he refused to fight Mosley until Floyd beat Mosley so in reality he does NOT take on all challengers, rather the easily winnable fights against popular "use to be good" boxers. Pac is not and never was the face of boxing, just the biggest threat to the real face of boxing.
