#1 Needing a legitimate contender for Lynch
Let's be honest here.
WWE needs some fresh blood in the women's division after Becky Lynch defeated Ronda Rousey and Charlotte Flair to become a double champion, and what better person to take on that role than Sasha Banks herself?
Not only would it allow for WWE to blur the lines between Banks' real life issues with the company, but it also could become the hottest feud in the women's division heading into the summer months.
Think about it! Natalya and Lacey Evans are maybe good for a one-off each, but it's nothing that's going to sustain the women's division long term. To do that, WWE is going to need to do something unexpected, and the only real ace in the hole they have right now is Sasha Banks and the attention she is gaining from her online actions.
If nothing else, this is what The WWE needs in order to turn the division on its head and really make things interesting again. Either that, or WWE can continue to do one off after one off for a while and try to establish a worthy competitor for Lynch, but it wouldn't be same as what Banks could do with the role.
