#2. Bargaining chip

Ronda Rousey may end up taking a hiatus from WWE after WrestleMania 35, but that doesn't mean she will be gone forever. In fact, depending on how WWE chooses to solve this little problem of Rousey not wanting to lose to Lynch, The Baddest woman on the planet could be interested in working with the company in the future.
Unfortunately for WWE however, they now must decide whether they want to put all their chips behind Becky Lynch as The Man, or give Rousey what she wants and get her back in the long term. Either way, the company is going to lose something special, which makes this a particularly hard decision to make.

In the end, maybe there's some kind of third decision WWE can make that sends everyone home happy. For example, maybe the company can have Lynch beat Charlotte and keep Rousey out of the decision entirely. At least that way, Rousey doesn't lose, is more likely to sign again with WWE and Lynch can have her moment.
