#4 Chad Gable

Chad Gable recently moved to Raw in the Superstar Shake-up and was separated from his tag team partner, Shelton Benjamin.
Hopefully, Gable is able to progress as a singles wrestler on the red brand. He showed promising signs of a singles run last year on Smackdown, when he had some fun matches with AJ Styles and Owens, during their feud for the US Championship.
Gable possesses natural charisma, which he has shown as both a face and a heel. He can be funny or serious, and people would buy into it.
His Olympic history further signifies the similarities between him and WWE Hall Of Famer, Kurt Angle. He can be a star, he has all the tools for it.
A match between Gable and Rollins for the IC title would steal the show on any given Raw. He is supremely talented in the ring and his character work is severely underrated. If he gets a chance to shine, he will take it with both hands and make the most of it.
