#9 The Shield reunites
They are quite possibly one of the most dominant and successful factions of all-time. They're certainly the best of the past decade or so. Seth Rollins, Roman Reigns and Dean Ambrose made an immediate impact upon their main roster debut in 2012.
Following their split, the trio went their separate ways and each had their own success in one way or another. The most impressive statistic since their split is the fact that all three have won the WWE Championship at least once.
In recent weeks, there have been a few teasers indicating a future return of the stable. Rollins and Reigns appear to be partnering up more often than not these days and Ambrose has found his way into the fold as well, from time to time.
Of course, the only way this works is if the brand-split ends, or they all somehow end up on the same show. Regardless, I do believe 2017 is the year of the return of The Shield.
