#1 Sasha Banks
Sasha Banks is a former WWE NXT Women's Champion and a 4-time Raw Women's Champion. She is one of the most talented women's wrestler of this generation. Her in ring skills are really good.
Due to some injuries Sasha has out of action for a while. But she has returned and is looking good. Sasha needs something new so that she can accomplish more things.
If she is drafted to SmackDown live in 2019, she can get new challenges such as Becky Lynch, Carmella and Charlotte Flair. There are some rumours about Women's Tag Team Championships to be announced soon, so she can go behind the titles with her tag team partner Bayley.
She is a good wrestler, a good performer, connects with the audience, etc. She just needs a push in more championship matches in future so that she can show more of her wrestling.
