1. Floyd Mayweather —
With or without 50 Cent by his side, the undefeated champ and his Money Team could be just the shake-up the rap game needs. Sure you have crews like Young Money, Slaughterhouse and those MMG guys, but Mayweather's foray into hip-hop's squared circle would shake things up. As the first pugilist rhymeslinger with a reality TV show on HBO, Floyd and his cavalcade of characters could rival DJ Khaled for most dopest studio guest appearance. If anything, we can at least expect Ray J to sit this one out on the bench!
