#2 Rey Mysterio (Won't)
Rey Mysterio is an absolute legend of the industry and was a pioneer in so many ways. He has been an inspiration and continues to be one today, with his timeless in-ring skills. However long he has left in the ring, we should cherish it, as Mysterio is a generational performer who transcends the business.
With that being said, WWE hasn't really treated Mysterio like a true headlining babyface. Sure, he won the 2006 Royal Rumble Match and captured the World Heavyweight Championship at WrestleMania 22. But he never really felt like a champion Md constantly lost matches on SmackDown.
Even during his brightest moments, Rey Mysterio was never painted as the most important guy on the show. That is a sign that WWE will not give him the headline spot at the Hall of Fame. He will be an inductee after retiring, probably as the second-from-top name in his Class instead of the top.
So when the time comes, the Hall of Fame might prove to be the final time we get to see Rey Mysterio steal the show from the undercard, as he has done on numerous occasions.
