#3 Shayna Baszler should remain on WWE RAW
Just like Belair, Shayna Baszler joined Monday Night RAW earlier this year. She had dominated NXT and had a strong showing at last year's Survivor Series. That strong run continued in the Royal Rumble and then the ensuing WrestleMania feud with Becky Lynch. She is currently one-half of WWE Women's Tag Team Champions with Nia Jax. While she could feasibly clean up on SmackDown, that's a big reason why WWE needs to keep her on RAW.
Baszler also fits into the RAW Underground scene as a former MMA fighter. She can support her friends, Marina Shafir and Jessamyn Duke, if and when they compete on future episodes. Being a WWE Women's Tag Team Champ means that she and Nia Jax can jump brands as the feuds suit them. Asuka still needs to have a showdown with Baszler as they were the last two women in the Chamber match.
SmackDown is called the "Land of Opportunity" in WWE and although it might sound a bit corny, it's true in some capacities. Which current Champions in WWE are more likely to have long title runs? Asuka (RAW) and Roman Reigns (SmackDown) are the two most likely names as Bayley should drop her title to Sasha Banks within the next month and McIntyre may drop his title to Orton.
If Baszler moves to SmackDown, it essentially means that the rest of the women will be her food. The Queen of Spades easily dispatched of most of the women once she showed up on RAW. In order to give the women of SmackDown a chance until another big name returns, Baszler should stick on RAW.
