This idea might not and probably won't happen, but I'm gonna throw it out there anyway: Say that Ambrose, Rollins and Reigns remain undefeated at Wrestlemania for the time being. They've won their first two Mania matches as a team and there's still a good chance that they could win all three of their singles matches next year as well (whoever those might be against.) I mean, we all pretty much figure that Reigns is getting the main event push and is walking away with the championship next year, so we know he's good. Let's assume that Ambrose and Rollins are, too. In that case, they could meet at the next year's Wrestlemania or the year after (that would be WM32 or 33), in a triple-threat match that may or may not be for the WWE Championship. It'd be cool to see all three men walking in undefeated on the grand stage to face one another in a match that will once and for all determine who the greatest member of their former unit The Shield is, in what ends up being the first loss at Wrestlemania for two of them at the hands of their former teammate.
