An unspoken WWE booking rule states that the man who ends the go-home show on top rarely wins at the ensuing PPV (or, in this case, Network special). While it's unclear quite how true that is, the superstitious among us won't be encouraged by the sign of Dean Ambrose again standing tall on SmackDown, days after getting the better of Triple H on Raw. Should he toppled the WWE World Heavyweight Champion at Roadblock, it will surely go down as one of the biggest upsets in recent years. Unfortunately, all signs seem to point towards victory for the King of Kings.
