There is no fuckin way he will pass up Bruno Sammartino, Bob Backlund, Hulk Hogan, or Pedro Morales.
Technically, Punk HAS passed them up as wrestling 4 times a year, like those guys did, is not an amazing feat. Let them wrestle the excruciating and painful schedule CM PUNK has and you'll see this. One month of his reign is equal to like a year of their reigns so you can basically say he's held the belt for over 12 years.
