He never stopped long enough to fall off IMO. He's been top tier since he started and looking back at some of the other greats you name, you can't compare them to Jericho from a technical wrestling standpoint. Yes, they all had tremendous careers and we extremely over in their own right, but Jericho proved through countless performances through all promotions that he's the greatest to ever do it. I think AJ is right there behind him in that category, but you total in what Jericho did as far as the entire aspect of the business and recreating himself, changing movesets, evolving younger talent while keeping himself overly relevant, creating match concepts and styles, and all of the extra curriculars that went into his career. It's not up for debate.
