After hearing the news of Jason Jordan missing WrestleMania, I had an idea about how Seth Rollins can be utilized going forward. Even though the plan has been Reigns vs Lesnar for the Universal Championship at WrestleMania, why not add Seth Rollins into that match as well? It would still be technically a rematch from Mania 31 and would satisfy quite a lot of people groaning at the thought of Lesnar and Reigns.
I would have a double pin/elimination in the Elimination Chamber match with Reigns and Rollins, or have Reigns win and Rollins finds a way into the match. They have a great match at Mania and Rollins wins by pinning Lesnar. The next night Rollins comes out for the victory celebration and is joined by Reigns. Reigns acts like he's congratulating his brother but then snaps and destroys Rollins using the angle that twice now Rollins has robbed him of the title at the big event.
