#1 The Miz
It seems clear that The Miz performs better on SmackDown Live than on RAW. Too often was the A-Lister lost in the shuffle on Monday nights.
On the contrary, on SmackDown Live, he has been a consistent upper-mid carder, feuding with the recently-returned Daniel Bryan.
In what many have considered a shock-upset, the Miz defeated Bryan at SummerSlam, so a WWE Title match may not be too far away. Having the Miz as champion really would elevate him, as his seemingly boundless charisma would make a very entertaining champion.
Furthermore, with one of the most well-known female WWE performers, his wife Maryse, by his side as well, the two would be a true power couple.
It has been over seven years since Miz was a WWE champion, and a surprise number-one contender win, or even a shock Royal Rumble win could be just what he needs to fling him back into the main event.
