According to The Wrestling Observer, WWE Tough Enough contestant Ivelisse Velez (known in FCW as Sofia Cortez), Raquel Diaz (real name Shaul Guerrero, daughter of Eddie and Vickie Guerrero), and Paige (Britani Knight), are seen as the FCW Divas with the most main roster potential.
Knight and Velez are seen as two of the best in-ring workers in WWE right now, with some saying they're both better than most of the current Divas on the main roster, and it's even being said that some are looking at Knight (Paige) as the future of the Divas division.
As for Diaz, she's said to be very green when it comes to in-ring work, but her charisma and mic skills are leading officials to believe that she could be a great personality in WWE.
In related news, it's also being said that Triple H is very high on Michael McGillicutty, real name Joe Hennig, who is the son of "Mr. Perfect" Curt Hennig.
