#4 Sasha Banks

Sasha Banks returned to WWE programming after a long hiatus from the company. Upon her return, Sasha went after an already-injured Natalya before assaulting Becky Lynch with multiple chair shots.
Even though the Boss returned as a heel, the WWE Universe couldn't help but get behind Banks. That tells you how over she is with the WWE Universe.
Look who just shut down all of Tony Khan's critics! More HERE.
Becky's title reign has been underwhelming so far and maybe a feud with the Boss could heat things up. WWE has to book the Boss very carefully going forward as she is one of the best heels in the Women's division.
#3 Buddy Murphy

After a brief stint with 205 Live, Buddy Murphy is now on SmackDown and he is showcasing his in-ring talents brilliantly on the Blue Brand.
Right now, he is involved in the storyline involving Roman Reigns and his mystery attacker. He faced both Reigns and Daniel Bryan in consecutive weeks and while he lost his match against Reigns, he won clean against Bryan.
In both the matches, he impressed with his performances and that has earned him great praise from the WWE Universe.
It seems WWE has high expectations from Murphy and we might see him getting a huge push and possibly even a title shot.
