Raw is having an issue with heels vs babyfaces right now because they can’t seem to get anyone to draw any real heat. Ronda Rousey is fine as a top babyface but they need someone for her to battle with that people care about.
It was discussed on Wrestling Observer Live how Natalya apparently injured her right knee one week and then sold her left knee the next. This was either an oversight or it was part of the storyline.
Bryan Alvarez noted that Natalya could very well be preparing for a heel turn on Ronda Rousey and her knee injury might be a way to get there. Nattie might be faking her injury in-character as a means to catch Rousey off guard.
This wouldn’t be the first time Natalya turned heel and some would say she works better drawing heat. Only time will tell what happens in this situation but don’t be surprised to see Rousey’s alliance with Natalya fizzle in some way sooner or later.
