#3 Lacey Evans (RAW)
Lacey Evans made her mark in the inaugural Mae Young Classic, where she reached the second round. Later she became a part of the NXT roster and feuded with the likes of Kairi Sane, Dakota Kai, and Candice LeRae. She is still fairly new in WWE, and has to build herself up from the bottom.
She is a former US Marine, and member of the Marine Corps Special Reaction Team, roughly equivalent to a civilian SWAT team, which transcends into her Lady Like gimmick.
For her individual growth, RAW would be a better roster to join. With opponents like Bayley, Sasha Banks, Natalya, and Ember Moon, Evans would find footing to establish herself on the main roster.
She would most probably be a heel when she settles down, but we could still see a clash against the #Facebreaker during her initial outing.
