3. Rob Van Dam
Some people will know that Rob was backstage recently at Raw to see if the company had any plans to use him at this year's WrestleMania. One scenario to bring him in would be after the IC title match as Jack Swagger and Zeb beat down an injured Big E. (don't call me Langston), Rob returns and saves the day - but not before hitting a Van Terminator. In one go you have moved Swagger into another program, given Van Dam a reason to be relevant for 6 months and let Big E. move up the card into a feud with, say, Sheamus. Either way, I would be shocked if RVD isn't back with WWE sooner rather than later.
