While I'm not sure how they go about turning his current character face, this is not a bad idea. Ryback is not working out as a heel, that much is certain. For most of his face run, he was over with the crowd and getting solid pops. I know he wasn't popular with most of the IWC (because, of course, he can't wrestle), but he was pretty popular with most of the crowds he performed before.
The biggest problem with face Ryback was that he ran into heel Punk and the Shield during a time when neither one could be beaten (even if it meant...*gasp*...cheating) and his character, which had been unstoppable, was suddenly stopped in its tracks.
