#4 Ronda Rousey is coming
Ronda Rousey-to-WWE rumours have been quite prevalent since WrestleMania 31 when she made a surprise appearance and helped The Rock stick it to Stephanie McMahon and Triple H.
Those rumours ramped up a bit when Rousey recently appeared at the tapings for the Mae Young Classic women's tournament and treated fans to a standoff between MMA's version of "The Four Horsewomen" and the WWE's. Throw in the fact that UFC president Dana White recently told ESPN that Rousey "is probably going to retire," and it sure seems like Rousey could be WWE bound at some point.
Although Rousey has struggled in MMA recently, she's still one of the most recognizable female athletes in the world and would be a perfect fit in WWE's women's division, where potential dream matches with the likes of Charlotte Flair and Asuka await.
It's a safe bet Rousey will at least appear in WWE in the near future, and an actual match isn't out of the realm of possibility.
