With speculation that UFC women's bantamweight champion Ronda Rousey, a noted professional wrestling fan who appeared on camera at WWE Summer Slam in 2014, could turn up at Wrestlemania 31, talk now turns to how the pro wrestling promotion might best utilize what could be a very brief, but well covered, cameo appearance. Rousey's been on a tear since entering the UFC, both in and out of the cage. She's undefeated in her MMA career, garners attention where ever she goes, has appeared in three major Hollywood franchises (with two of those films yet to be released), has been on the cover of ESPN's The Body issue, and is featured in the upcoming Sports Illustrated Swimsuit Issue as well. Oh, and she just made Maxim's Hot 100. Not bad for someone who, just a few years ago, was doing silly little things like winning Olympic medals and blazing a trail in women's MMA. In short, Rousey has been a huge success, and is a huge star. TMZ started covering her when they were barely interested in the MMA game. Mainstream media pays attention to her. Having her appear at Wrestlemania, as the McMahon family might say, is best for business. In what capacity though? Well, lets take a look at five ways the WWE could use Ronda Rousey at Wrestlemania 31!
