The Shield had a huge impact on the WWE, and while Seth Rollins, Dean Ambrose, and Roman Reigns are all focused on making a name for themselves as singles competitors right now, some sort of reunion or team up between this trio is an inevitability somewhere down the line (as is a Triple Threat featuring all three men going to war with each other hopefully). If Reigns and Ambrose are going to remain babyfaces, having Rollins turn nicely sets the stage for him to rejoin them even if it's just a one off. Can you imagine a babyface Seth Rollins squaring off with Brock Lesnar at SummerSlam only for The Shield to appear and help him win? That's why this needs to happen at some point in the very near future...
