#2 Drew McIntyre
At one point, prior to being thrown into 3MB along with Heath Slater and Jinder Mahal, WWE looked at Drew McIntyre as a future cornerstone of the company. In fact, some people believed that he'd end up being the next Triple H.
Now that he's back and has been put in a pretty significant spot alongside Shane McMahon, it's quite clear that the company's faith in McIntyre has been restored. On top of that, you could argue that pro wrestling's most hardcore fans want to cheer for the "Scottish Psychopath," as they're fully aware of how talented he is and what he could potentially end up becoming if pushed properly.
At some point, the idea probably will be to have McIntyre turn against Shane McMahon, which will probably end up making him one of the most popular faces on the roster. He might not get the best matches out of Vince McMahon's son, but it would start his run as a good guy off right.
