#1 Chris Jericho
Chris Jericho is the hottest free agent in the wrestling world today. Even at 48 years old, he can still give wrestlers half his age a run for their money. Jericho is the only wrestler who competed at both WrestleMania 33 and the Wrestle Kingdom 12, the two biggest shows in professional wrestling.
It's been close to a year since Jericho had a full-time contract with WWE. He only had a backstage segment at RAW 25. Jericho is currently on tour with his band, Fozzy. His show on April 8th coincides with the date of WrestleMania 34, which gives him the occasion to return to WWE on Monday Night Raw.
The WWE Universe will love to see 'The Ayatollah of Rock n Rolla' back in the company, even on a part-time basis. He is one of the most loved performers of all time, and his returns come with plenty of hype and excitement. His last run with the company was one of his best, and WWE would surely want to capitalize the opportunity on Y2J.
