So, after seeing Kevin Owens vignette on Raw, he seems to be returning as a babyface and possibly on Smackdown. It's gotta be Bryan vs Owens at Mania, right? And you can even have Sami return, torn between his best friend and the fact that he agrees with everything Bryan is saying and doing. That's a storyline you can run for a while.
I don't know if I'd be feeling that particular storyline. Owens was such a flop as Universal champion that I don't really think sticking him into a World title program immediately upon his return would be something that people would buy into.
