I don't believe these dirt sheet rumours at all anymore. They've said that about Eva Marie for years, for example. It's supposedly all about her but on television I've seen very little evidence of it. See 20 years ago when the internet was more scarce and talent/crew/promoters didn't leak insider info every day, dirt sheets were relevant, now they just play guessing games with things they heard from irrelevant people and hedge their comments by saying 'of course that could change' - which it always does. Time for Meltzer to retire or find a new angle. Alvarez too, although he's worse. Bottom feeders who don't even have access to the trash chute anymore, if they ever did.
As far as Eva Marie goes:
I think what Smackdown is actually gonna do is have her win the upcoming Smackdown women's title, without ever really wrestling and being defended by an entourage, while Becky chases her. Eventually Becky takes it from her in a situation where Eva Marie has to take her on one on one. That could be their Mania match, a 3 minute squash where Becky just gets her moves off on Eva.
I think that'll be a fun program. If Eva is capable of cutting promos about how great she is, that's all you really need. Have Nattie and a couple other women always be backing her up and fucking with Becky. Eva has a certain type of heel heat it is hard to manufacture.
