#2 The breaking of the streak
Originally, Undertaker was slated to defeat Brock Lesnar and advance his WrestleMania undefeated streak to 22-0.
Reportedly, Vince McMahon changed his mind at the last moment, and it was decided that Brock Lesnar would break the streak that had lived on for two decades. Apparently, Vince thought that this could be The Undertaker's final match and he wouldn't be able to perform at his age going forward. The boss couldn't have been more wrong, as we're in 2019 and Undertaker is all set to appear at the Saudi show.

The ending of the streak will go down in the history of this business as quite possibly the most shocking moment of all time. It also marked the beginning of the end for The Undertaker, who deserved to go out with his head held high after years of service to Vince McMahon and WWE.
