#3 An Underdog Story

If there is one thing that the WWE fanbase love, it's an underdog story, and having Seth Rollins finally be the one to dethrone Lesnar would certainly provide fans with that.
The Beast Incarnate has demolished all of the big men on Monday Night Raw. He has made quick work against the likes of Samoa Joe and Braun Strowman, and he destroyed Roman Reigns at WrestleMania, even if it did take multiple F5's to keep The Big Dog down.
Look who just shut down all of Tony Khan's critics! More HERE.
Rollins is very much the man of the moment in the WWE, and a big reason for that has been his inspired, iron-man performances in the ring this year. Rollins' performance in the Gauntlet match back in February this year was reminiscent of something we would have seen from Shawn Michaels or Daniel Bryan back in the day, and the fans were lapping it up.
Seeing Rollins endure a beating from Lesnar, only to finally keep him down with the Curb-stomp would make for excellent viewing and could even potentially drag a match of the year candidate out of Lesnar.
Overcoming Lesnar in a gruelling battle would not only get Rollins over massively, but it would also play into his current character well, and would even make his victory feel believable, which is perhaps the biggest stumbling block for the WWE when it comes to dethroning Lesnar right now.
