#3 Bayley and/or Sasha Banks
Bayley is obvious, but Sasha Banks has lost most of her momentum also. Sasha will be part of Raw's women's Survivor Series team, but with Asuka also there and a returning Paige possibly to follow, her chances of making a notable impact on that show are slim, and Bayley's spot would obviously be taken.
In fact, it would be better if Bayley didn't make Raw's Survivor Series team. That way we might actually feel something for her, sharing in her disappointment. Perhaps it could also lead to the anticipated rehash of Sasha and Bayley's NXT program, which both of them could very much use.
Either way, one of them needs to change. Hopefully, that change would go on to elevate the other in a program. They might be real-life BFFs, but that should be kept backstage for now, as it hasn't taken them anywhere on Raw in the past year.
