It's been said that the original plan for Kevin Owens at WrestleMania was for him to challenge Daniel Bryan for the WWE Championship. However, the rise of #KofiMania changed the company's plans and, as of right now, the former Universal Champion has nothing to do at the Showcase of the Immortals.
He's not even been booked for the annual Andre the Giant Memorial Battle Royal and Owens has taken to social media to explain that, yes, not being part of the PPV is driving him crazy!
With any luck, WWE will find a role for him and I'm sure they could squeeze in an episode of the KO Show. If not, there's a very good chance that Owens is going to end up missing WrestleMania and that seems like a tremendous waste. However, that's one of many downsides of having such a packed roster.
