#1 CM Punk
If there is anyone who can beat the pop that Daniel Bryan will get, it is CM Punk. "The Voice of the Voiceless" walked out of the company on January 27, 2014. His contract expired and it wasn't renewed. Despite announcing his retirement and claiming that he is done with professional wrestling, fans all around the world are still hoping that one day, they might hear the song, Cult of Personality.
After leaving WWE, the self-proclaimed "Best in the World" signed with UFC. Many questioned his decision and were not sure if it was a brave one or a stupid one. At UFC 203, Punk lost to Mickey Gall at 2:14 via a rear naked choke.
Punk's dismal performance once again opened the discussion of him returning to professional wrestling.The last time we saw "The Second City Saint" in WWE was also Royal Rumble. Coincidence? I think not.
