#1 Elias
Elias made his main roster debut this year on the April 10th edition of Monday Night Raw. He was just playing out his character as a drifter musician making random appearances during the matches and other segments. Most people would've thought that WWE is bringing in a new jobber to be fed to their main event players, and it was turning out to be true.
Elias was jobbing to Jason Jordan and was involved in underwhelming matches like the Guitar on a pole match. However, the WWE Universe got to see the real talent in Elias when he answered Roman Reigns' intercontinental championship open challenge on the November 27th episode of Raw. He gave reigns a very tough fight, and to be honest, no one saw it coming from the drifter.
It looks like a strong possibility that Elias has caught the eyes of the WWE higher ups, we can expect him to be booked in a strong fashion in the future. A run with the Intercontinental Championship will do wonders for the drifter as he has all it takes to portray the role of a natural heel champion.
