It is no secret that Chris Jericho's latest run with World Wrestling Entertainment has been disappointing. His matches have been the normal, excellent Jericho fare, but everything else—from his promos to storylines to the videos hyping his return—has been rather uninspired.

This Sunday is  Jericho's final appearance for WWE before heading out on tour with his band, Fozzy. Chris has the opportunity to erase any disappointment fans may feel about his 2012 and any questions fans may have about his dedication to professional wrestling by passing the torch to Dolph Ziggler in a show-stealing match at SummerSlam.

While most would consider a Chris Jericho versus Dolph Ziggler match to be a given for a show-stealer, that may not be the case here. Jericho's two WWE Championship matches with CM Punk, while excellent, failed to reach the heightened expectations fans had for them. His other matches were also "very good," but none reached the level of greatness associated with Y2J.

Sunday night, he must prove that he has not, as Ziggler has claimed, "lost his touch." He must prove to the fans that his return was not merely a stopgap between Fozzy tours. Most importantly, he must prove to everyone—himself included—that he is still "the best in the world at everything he does."

If he does not, if Jericho cannot match the expectations fans have for a match between two men considered to be two of the best workers in the world, then his return will be remembered for what could have been rather than what was.
