#2 Corbin defeats Angle
Now hold on a second, let's all stay calm. I don't want this to happen either, but it's possible. It's pretty clear that no one wants Baron Corbin to be the person that retires Kurt Angle but it's happening.
Everyone would rather have Kurt win but it's a definite possibility that Corbin picks up the win to anger the fans at Metlife. Let's hope Vince sees sense and books Kurt to win.
#1 The Rock returns
The Rock has not appeared at WrestleMania since WM32 in Dallas, so it has been a while for The Great One. In his last appearance, he beat poor Erick Rowan in 6 seconds, so that probably won't be the last match we get out of him.
With Elias' concert, it seems made for an interruption and Dwayne is the perfect pick considering his musical exploits in the past. He has previously performed a few rock concerts on Raw to entertain the crowd.
The Rock sending Elias packing would be a good 'Mania moment and would maybe make all the time Elias will spend on the show worthwhile.
