#3 Ember Moon
RAW has a really deep women's division and it will only get more crowded after WrestleMania. Becky Lynch is almost certain to move to Monday nights and it's possible that Charlotte Flair could also join her. The latter depends a lot on what WWE's plans for Flair at WrestleMania are.
With a division that deep, a lot of talented Superstars may not get enough time and one person WWE can't afford to let that happen to is Ember Moon. The Shenom has an incredible future ahead of her and but to reach her full potential, she needs time and exposure.
On SmackDown Live, Ember Moon can quickly become one of the top challengers for the SmackDown Women's Championship. It also opens up the fact that we'll see a lot of fresh matches for Ember Moon including against Carmella, Mandy Rose, Naomi a, d Asuka.
