I feel like given all the injuries, plus so many women in tag teams, that they don't seem to have enough to cover all 3 divisions. Raw, SD, and tag champs.
Alba and Isla obviously a tag team but often they just throw people together like Bianca and Jade, Shayna and Zoey, Chelsea and Piper. I doubt Bayley defends until SS.
Liv had the cage match with Becky but i don't think she has any real competition over on Raw. Unless they waiting for Rhea to come back since they just have her messing with Judgement Day and Dom, and with Buddy possibly injured, who's to say Rhea may not choose to take a bit more time off at least until SS, that's if she's cleared by then.
They need to either split teams up or let the women go between brands to give a variety of matches and challengers.
