WWE SummerSlam 2016: 6 Big Matches That Must Happen (And How To Book Them)
3. Seth Rollins Vs Brock Lesnar (#1 Contender's Match)
Seth Rollins is set to return from injury in the very near future, and upon his return he will be cheered by the WWE Universe. Since he never actually lost his title to anyone, Rollins should once again be back in the WWE Championship picture.
With the Co-GM situation that is currently being played out on WWE TV, Seth Rollins could figure right into those storylines. A scenario in which Rollins will go to Shane McMahon looking to get a WWE Championship match. Enter Stephanie McMahon, and perhaps a returning Triple H (who Seth was rumoured to face at Mania prior to his injury, as the two were starting to become at odds with each other), and they feel that he shouldn't just be given a WWE Championship match, and that he needs to earn it.
Stephanie says that there is another superstar, and former WWE Champion, who has been away but is also set to return. In comes Paul Heyman, the advocate for Brock Lesnar! She sets up a match between Seth Rollins and Brock Lesnar at SummerSlam, the winner becoming the #1 Contender for the WWE Championship.
This could be a perfect way to write in three major superstars (Triple H, Seth Rollins, and Brock Lesnar), and place a great significance on their big match.
