6. The Dudley Boyz
http://en.wikipedia.org/wiki/File:Team3D.jpgThe WWE have been notoriously reluctant to promote tag team wrestling in recent years, an especially confusing stance given the surplus of talent sitting around the undercard with very little to do. A Dudleys appearance could well provide the spark the tag division needs to get back on its feet again, a risk-free decision after Bubba Ray's popular entry in the Royal Rumble a couple of months ago.
Potential Role: Probably the Battle Royal, as well as some backstage interaction with Paul Heyman.
