#2 The Rock
The last time we saw The Brahma Bull at WrestleMania, he and John Cena took on The Wyatt Family in a pretty long segment at WrestleMania 32.

With Elias not being featured in a match as of now, it's safe to assume that he might perform a song or two in front of 80,000 roaring WWE fans. As always is the case, Elias is going to get interrupted at WrestleMania. Why not let The Rock come back for a one-off segment with Elias and give us a good old Rocky Concert, the kind we got on an episode of Raw in 2003?
The segment would possibly end with Elias getting a People's Elbow, but a 15-minute segment featuring The Rock and Elias is always better than listening to a band perform and hog the spotlight in a worthless segment. If The Rock is coming back at MetLife Stadium, there's little doubt he will have a face-off with Elias.
