Now that I think about it, it IS interesting that Heyman approached Haitch and Steph BEFORE the main event and THEN Rollins gets "injured"...it's risky, but it could be a way to instigate a Rollins face turn.
One theory I've always had is that WWE is doing with the Shield what they never did with Bryan and Kane (where Kane was supposed to be Bryan's "man on the inside" in the Authority); except in this instance it's Rollins who's the mole. So Lesnar beats Cena at Summerslam, Reigns comes out and spears Lesnar, Ambrose hits Dirty Deeds, then the old "Sierra Hotel India Echo Lima Delta" hits, Rollins emerges with the briefcase. Cash-in, Curb Stomp, Champion, reunited Shield.
