Should Mosley and Berto still fight now?

This would be a great fight to see if Mosley should continue fighting or not. He didn't look his best or even the same guy that beat Margarito, but that was because Floyd is Floyd and that's what he does to his opponents. This could also be a coming out party for Berto. Of course the victory wouldn't be as big as it would have been in January since Mosley just lost to Floyd, but then again Berto is no Floyd, so this would be the fight that would give Berto mainstream coverage and possibly put him in the top p4p list. I think Mosley still has what it takes to beat Berto. I also want to see Mosley win again before he retires.
