5 reasons why Ronda Rousey interfered in the SmackDown Women's Championship match 

#1 Because she has no credible challengers on RAW

All of her potential opponents are currently on SmackDown Live, at least the credible ones!

Ronda Rousey has made short work of Alexa Bliss and Nia Jax, meaning there aren't too many credible opponents for her on RAW right now. I love Sasha Banks and Bayley but considering their current booking, can you honestly dub them credible challengers for the RAW Women's Championship? The same holds true for Ruby Riott and Natalya. All of Rousey's big feuds are on the other brand, going forward.

And this is why Rousey took the first step to establish herself as a thorn in Flair and Lynch's side. It is clear that these women will meet down the line, based on how the Royal Rumble plays out. Rousey could have a few more matches on RAW, but will anyone believe that anyone else from RAW can conceivably beat her? I don't think so.
