The Rock has been making the media rounds in the last couple of weeks because his new movie Hercules is being released next Friday. Whenever he does these interviews he always gets asked about going back to WWE. A few days ago when he was asked on ESPN he said "possibly yeah" to the idea of coming back to WWE. It was more than the words, though. He said it with a smile on his face as if something is in the works. Let's make something perfectly clear. If The Rock comes back for one match it's only going to be at WrestleMania. In 2013 he wrestled three matches and that was great, but that's probably not happening again. If he does return it's only going to be at WrestleMania 31 and it will be on his terms. There's no guarantee that he will wrestle again. He may realize he's too old for it. Maybe some Hollywood people will tell him not to do it because of the injury risk. There are a number of factors that could come into play, but what's most important is whether he wants to do it. It appears as though he's very interested in it, so with that in mind it's up to WWE to come up with something for him to do. That's easier said than done. Here are seven reasons why we believe The Rock is going to wrestle at WrestleMania 31.
