#2 The Miz

The Miz stunned the whole world when he decided to cash in his Money in the Bank contract (which he won at 'Money in the Bank' PPV) upon Randy Orton at an episode of RAW. He became the WWE Champion for the first time in his life and had a tremendous run as the Champion. He held the title for 159 days and defended against multiple superstars.
One of the major reasons behind Miz's success as WWE Champion was the constant support of Alex Riley. They both together feuded and fought against every possible superstar in the locker room. Finally, the Miz lost his title to John Cena. Miz is currently in the RAW brand of WWE and also the reigning Intercontinental Champion. If he returns to SmackDown as a part of the Draft, he can feud for the WWE title against any and every superstar in the brand.

Miz has promised that 2018 will be his year, and it will be enthralling to see if he can win the WWE title again.
