#4 Horsewomen feud
The seeds have constantly been planted and the constant interactions between Ronda Rousey and members of NXT's Four Horsewomen have all seemed like they were setting up a feud in some way.
All members of the NXT group have battled Rousey in one form or fashion in the last year or so.
Although it may not happen at WrestleMania 35 or right after it due to Rousey taking a hiatus from the ring, a feud between the two factions of Horsewomen is certainly possible to occur in the second half of the year.
Marina Shafir and Jessamyn Duke are still learning on the job in NXT while Shayna Baszler is more than ready to join the main roster.
She might even lose the NXT Women's Title on WrestleMania weekend and debut on the following Raw or SmackDown.
When Rousey eventually returns, it would be easy to kick things off if she returned as a heel with her heel friends.
The fans will always cheer Becky Lynch and most of the rest of the Four Horsewomen of NXT, so it wouldn't be hard to have people invested in a potential feud.
Not to mention that it could either main-event a PPV or the second iteration of the Evolution PPV in the fall.
The women are still on the upswing in WWE and a huge feud between the two factions will keep things going that way.
