#5. WWE is filling WrestleMania with more last-minute matches
WrestleMania 36 host and newly-signed WWE Superstar Rob Gronkowski opened the show along with Mojo Rawley. His music was awful and we hope they change that, but the purpose of his appearance was to help build another WrestleMania match.
King Corbin interrupted Gronkowski and started trashing him and Mojo, with the former NFL player suggesting that he face his current rival Elias at WrestleMania 36. While Corbin denied it, Elias accepted it and it appears as though the match is official.
Elias will finally get his first match at WrestleMania after 3 years on the main roster. It's a bit surprising that they haven't gotten him on the card before, but his appearances at WrestleMania 34 and 35 were in a non-wrestling capacity - as he confronted and was then confronted himself by John Cena back-to-back.
Both occasions saw him take the fall, but this year he's a babyface and WWE is making sure to fill-up the two-day WrestleMania with as many matches as possible.
