Hard to justify Margarito retaining top spot if he loses to the faded Mosley (or loses at all, for that matter). Edit: So, yes, I suppose Mosley would be "the man" at that point. Which... Cotto already beat Mosley, so there is definitely some muddy water right at the top of the division.
Anyone who takes illegal substances in a combat sport to gain an unfair advantage is more than a cheater.
depends on how mosley beats him, then we can go from there. if he ko's margo, pw better run for the hills. if he stops margo, has a good chance to beat pw. if he barely gets by, he might get a draw. but whoever wins here, should fight pw for ww supremacy once and for all.
