Five days before he headlines the main event on The Grandest Stage of Them All for the first time, Daniel Bryan officially celebrates 100 days of his uninterrupted reign as World Heavyweight Champion. The submission specialist’s undeniable talent has not only made him a formidable challenge for No. 1 contender Sheamus at WrestleMania XXVIII, but his sustained success elevates Bryan’s achievements into an elite class of impressive World Heavyweight Title reigns that includes The Undertaker, Edge and Rey Mysterio.
