Rey Mysterio had an incredibly successful career in WWE. You could argue he was one of the top 20 babyfaces in the companys history (though he had no business being ranked above Hulk Hogan, Ric Flair and Gorgeous George on that that top 50 Superstars of All-Time DVD...thats a whole other article). Hes one of the few wrestlers that even non-fans find cool. After a horrendous, embarrassing past few years, Rey went out on a real down note. He racked up a couple wellness policy violations, he gained weight, he slowed down, he paired up with Sin Cara in a mediocre team, and then lost to Bad News Barrett the day after WrestleMania last year. That was the last we saw of him. Now hes gone. It sounds like Rey had a falling out with WWE management the past few months, and had no desire to ever come back. Its unfortunate, as instead of being able to put someone over on the way out (say a Sami Zayn, Kalisto or Adrian Neville) in a final, great program, he went out with no fanfare. From an on-air standpoint, its another disappearance that will never be mentioned, much like The Great Khali, Mr. Kennedy and DLo Brown. Best of luck Rey wherever youll jump out the sky next.
