WWE was wise to give viewers a hook last week, announcing a WWE World Heavyweight Championship title match on Monday night. Roman Reigns will defend his title against former champ Sheamus, with chairman Mr. McMahon serving as the guest referee. If that doesnt trigger alarm bells, then you havent been watching professional wrestling for very long. McMahon wants the title off Reigns in the worst way, and rather than stripping him of the championship, he wants to screw Roman out of it in the middle of the ring. That means stacking the deck against the champ. So dont expect a biased ref to be the only obstacle for Reigns to overcome. What else could happen, and how much is too much? It wouldnt be a surprise to see the League of Nations get involved, but what about a returning Triple H? Maybe Brock Lesnar (as mentioned in the previous item) decides that he wants back in the title hunt and announces himself at an inopportune time (though highly unlikely).There also is the likelihood that evil ref Mr. McMahon changes rules on the fly to prevent Sheamus from losing. The game will be in keeping track of all the ways the deck is stacked against Reigns.
