#1 Ronda Rousey - Smackdown Live

Finally, at #1 on the list, we have the Rowdy one herself, Ronda Rousey. Rousey is currently the Raw Women's Champion, and she has had a fantastic run on the Raw roster so far. She started off in a rivalry against Stephanie McMahon and Triple H alongside Kurt Angle in a feud that put Rousey over in the best possible way.
Despite winning the Raw Women's title quite early in her WWE career, you can't deny the fact that she has yet to disappoint. Every single one of her matches has been great, especially with the WWE putting in the effort to make sure that she is believable as the champion. She has beaten most of the women on the Raw roster, from Nia Jax to Natalya to Alexa Bliss.
In late November 2018, there were exclusive rumors in the wrestling world that stated FOX wanted Ronda Rousey on the Smackdown roster when Smackdown Live moves to the huge network in October 2019. With FOX wanting Smackdown to be more of a sports direction instead of comedy, they feel as if Rousey's credibility and popularity would be the perfect way for viewers to tune in.
There is still obviously plenty of time before October 2019, which suggests that WWE might not even draft Rousey to Smackdown any time soon. But with Smackdown having the likes of Becky Lynch, Charlotte, and Asuka on their roster, what better way for Rousey to improve and increase her star power by going up against the very best?
