#2 Roman Reigns
Ever since the Superstar Shakeup ended, the entire WWE Universe has been fearing the sight of Roman Reigns beating Kofi Kingston for the WWE Championship. It might be a stretch because both of them are babyfaces.
Surely management would not throw away all the goodwill that Reigns has garnered over the past six months. He is still getting cheered and will continue to be, as long as WWE keeps him away from Kofi Kingston's WWE Championship reign.
If Reigns does win the title from Kofi, he will likely get booed even worse than he has up to this point. And he has had it bad in the past. It seems pretty obvious that the Big Dog will become the WWE Champion by the time Smackdown goes to FOX, it is just a matter of who he beats. But as long as he is healthy and on the roster, Roman Reigns will always instantly be one of the frontrunners to be the next world champion. This situation is no different.
