Re: If CM Punk held the title until July 25, 2019....
Wouldn't happen, he'd run the WWE out of business.
Seriously though, how in the fuck can you see this as a possibility? He's not big enough a draw for that to happen, and people today including myself have short attention spans so we'd get really sick of him being champion for so long--hell a lot of people even now are annoyed with him being champion for as long as he has been.
The thing is, he doesn't need to be a draw to stay WWE champion. Does the show truly center itself around the WWE champion or around who draws more? Why not keep Punk champion for a very long time, and allow others to outshine him here and there - those will be the draws.
