Questions:

Floyd Mayweather Jr. Retired and vacated the Ring Belt. Shouldn't have Mosley vs Margarito been a box off for the vacated Ring title? Wasn't Mosley ranked #3, Margarito #1 and Williams moved up?

So now we have Mayweather un-retired and facing Marquez and The Ring title is still vacant, shouldn't the title belt be on the line since the fight is being made within the weight class?
