#3 Mandy Rose
It's no secret that WWE has been inching towards more mature content lately, especially with the addition of the ongoing Maria Kanellis saga. One could imagine them doing this more often, especially with new competition on the horizon. Fortunately for Mandy Rose, who Vince McMahon has already been high on, that could mean some interesting storyline opportunities in the future.
While it's doubtful that WWE would go back to The Attitude Era-style "Bra and Panties" matches of the past (McMahon even refuted such a move in a recent media call), Rose's looks will go a long way in bringing in casual fans. Combine that with her amazing abilities as a heel and her growing body of work in the ring (no pun intended), there is virtually no limit to what WWE could do with her.
In the end, it will never be The Attitude Era. It will never be like that time that Vince McMahon caught Shelton Benjamin in the shower and exclaimed, "are you ready for some wrestling?" What it can be however is a more mature version of The women's revolution, which Rose would certainly thrive in
