So here's the thing.
Logan Paul is not a celebrity performer. He's a WWE Superstar at this point and to say otherwise is disingenuous. McAfee has been with WWE for over 6 years now. While the 2 are famous outside of WWE they don't belong in the celebrity involvement aspect.
Speed and Jelly are the 2 celebs we're talking about. Jelly has been absolutely incredible in the builds. He's real good on the mic. In-ring he's fine for a celebrity. Speed who knows. Dude is athletic so figure the in-ring with be adequate and he's been pretty decent so far with what they've done with him outside of the bell.
WrestleMania 1's main event had an actor in the match, a baseball manager as ring announcer, a whatever the hell Liberace was as a timekeeper, a musician as a manager (who was incredibly involved in the buildup). So I don't see the issue with celebrity involvement at WrestleMania, even in main events.
In a perfect world, I would have had Cody/Randy at the Rumble as Face/Face, with Cody going over clean. The then the McAfee involvement and the heel turn works better. But they needed to give Drew a title run so that's what they did.
