If Rock/Ryback happens, this can also be their "out" for Ryback's streak, because it obviously can't go on forever and like The GOAT himself said:
Nobody is losing any credibility when they're in the ring with The Rock. I'm sure that Rock will also bump for him and will make him look better than ever, like he did to all of his opponents his entire career.
Ryback is not facing Rock, it's just not happening. Rock has made it clear he wants to face Punk, he probably has no idea who Ryback even is.
Ryback/Rock would suck ass, they would make Rock hold back on the promo's because he'd make Ryback look like shit, plus Ryback can't talk, so he'd never give any rebuttals excpet "Feed Me Rock" Plus they are trying to make Ryback the next big babyface, why put him in a match where the crowd will turn on him?
It's gonna be Punk vs. Rock, and thank fuck for that, if they let both guys perform to the top of their ability, it will be amazing.
I know you hate Punk, but even you have to see why Punk/Rock is a much smarter plan and will have MUCH better results.
