Pac's got 3 more fights in him. Mosley can get it first. Then Bert/Alexander/Marquez. Then if Floyd isn't doing time or has regained his balls, his final fight can be against Floyd. If not Floyd, Pac caps his career with Marquez III.
I just would like to see him fight a boxer, a real mover that is fast! all that they always feed him is guys that stand in front of him other than Marquez and to a degree cotto is just the same style he faces not saying he can't beat them but it would be good to see him face a guy like alexander, it even will help him somewhat for a possible fight versus Mayweather.
