7. Rob Van Dam
The 43-year-old RVD doesn't have that many years left in pro wrestling, so if it were me I would strike while the iron is hot. Take advantage of every opportunity you can to be in WWE. In two years the phone may stop ringing. If it's ringing now, the smart thing to do is answer it and get back to WWE to have one more run. Van Dam has said on Twitter recently that he did have an interest in coming back to WWE. It's a possibility that he could be a surprise participant in the Andre the Giant battle royal since WWE is probably going to have a few open spots in the match. While it's unlikely that he would ever get a serious push since he's content with working for just 90 days, his name still has a lot of value. He's a big enough star that if a heel on the rise beat him in a match it would help that person look like a bigger deal. In a few years we may not be able to say that about. If he's smart, he'll be back in WWE sooner rather than later.
