War Raiders (c) vs. The New Day vs. LWO vs. American Made [World Tag Team Titles]
War Raiders have been dull champions, and New Day have never won as a tandem at Mania. They deserve their flowers after a prestigious 10-year run, and they also should solidify their heel turn on Big E by winning tag gold at the biggest stage. LWO and American Made have their own feud going on and will likely cancel each other out. WWE would be unwise to waste that New Day heel turn, as it could become one of the greatest heel tag title reigns in professional wrestling today. It would also be glorious for Kofi and Woods to rub the titles in Big E's face on the panel to elicit more nuclear heat.
Prediction: New Day
LA Knight (c) vs. Shinsuke Nakamura vs. Jimmy Uso vs. Solo Sikoa vs. Braun Strowman vs. Jacob Fatu vs. Andrade vs. Carmelo Hayes [U.S. Title: Ladder Match]
There are good arguments for Jacob Fatu or Carmelo Hayes to win this match. Fatu has been elevated recently due to his hot Bloodline feud with Sikoa, but he still has a story to finish with Sikoa before winning gold. Hayes has consistently been losing, but he is an NXT call-up who needs this swerve victory to establish himself on the main roster like Breakker, Stratton, and Valkyria have done. However, LA Knight just won the U.S. Title back from Nakamura, so it would be quite nonsensical for WWE to make him a transitional champ in his second reign after already ruining his first.
Prediction: LA Knight
