#2 Ronda Rousey and Shayna Baszler
Well, this one might be the most predictable on the list, but with Rousey currently holding the Raw Women's Championship, it is a bit of a wildcard shout. This one may require Rousey doing double duty or dropping her title - and a massive NXT call-up.
While Natalya may be the more likely partner if Rousey is in contention for a tag division role, Baszler could be perfect for long-term storytelling. Ronda Rousey is by far the biggest name to make the switch from UFC to WWE, but the NXT Women's Champion made that same journey before her friend.
As Rousey has been learning how to ply her craft in WWE in front of the world, Shayna Baszler learned behind closed doors and has been honing her craft between the yellow ropes ever since - even claiming the runner-up spot in the Mae Young Classic with Rousey watching in the front row.
When Baszler won the NXT Women's Championship at TakeOver, Rousey was there to congratulate her backstage. Now, if WWE really wanted to go all in with this pair, give them the Tag Team Championships, then let Baszler turn on Ronda Rousey to set up the ultimate UFC fighter turned WWE Superstar rivalry!
