#1 The Miz

Do you remember when the Miz destroyed both John Cena and Roman Reigns in the same segment on being given unfair opportunities? Though it's a part of the script, it's sure he meant everything he said.
He’s been with the WWE for 15 years as of now, and looking back at his career, he would only be remembered for his eight reigns as Intercontinental Champion.

When Brock Lesnar made sporadic appearances while being Universal Champion, it was The Miz who gained some interest towards the show as the only singles champion on Raw.
His only WWE title reign came in 2010, but it didn't get the deserved spotlight as it got overshadowed by the feud between John Cena and The Rock.
WWE should make up for their failure with the Miz's first WWE title reign and pull the trigger on the A-Lister to get a proper stint with the WWE / Universal Championship.
