#2. John Cena - Does a WrestleMania 37 appearance make sense right now?
John Cena had an intriguing cinematic style match against Bray Wyatt at WrestleMania 36. It wasn't even a match at all, but with John Cena just vanishing, it appeared that Bray Wyatt got his revenge from WrestleMania 30.
Since then, John Cena has been absent from WWE, and there doesn't seem to be anything in place for him to make a return for WrestleMania 37. While he will always be a legend that fans want to watch, WWE may hold off until WrestleMania 38 when crowds are back so he can return.
#1. The Undertaker
The Undertaker had an unexpectedly perfect farewell match at WrestleMania 36. He main-evented Night one of the two-day WrestleMania, and his Boneyard Match was largely considered the best match of the entire pay-per-view.
It was a fitting farewell to his career. Not only did he return to his "American Badass" persona one last time, but his final match at WrestleMania took place against AJ Styles - the best in-ring talent of his generation.
After saying goodbye to the WWE Universe at Survivor Series 2020 (30 years after his debut), it appears as though The Undertaker is well and truly done with any future WrestleMania appearance.
