#2. The setup for The Undertaker vs AJ Styles
The opening contest of the night was the Gauntlet match to crown the winner of the "prestigious" Tuwaiq Trophy. The commentators emphasized how "prestigious" it was, yet it was a complete afterthought.
Ultimately, what happened was that R-Truth had a good showing, eliminating Bobby Lashley, Andrade, and Erick Rowan before losing to AJ Styles. The Phenomenal One was supposed to face Rey Mysterio at the end, but Gallows & Anderson assaulted the legend.
The duo would soon be struck down as well and it was The Undertaker who took Rey Mysterio's spot, hitting AJ Styles with a single chokeslam and winning the Tuwaiq Trophy. Except, at this point, the trophy didn't matter at all and he hardly took in a glimpse of it.
It was just a prop to build to the Styles-Undertaker WrestleMania match. They could have done it differently and built towards it from RAW rather than use the trophy to set up the match for the show of shows.
