Triple H will have a say in the WWE Championship match
Triple H, like him or not, is the one who calls the shots nowadays. Unless Vince McMahon comes back, the WWE Universe is stuck with him.
Being the egomaniac that he is, Triple H would love to stamp his authority on the WWE Championship. And there is no better way to do that besides deciding the outcome of the match itself.
Daniel Bryan, being the crowd favourite, is bound to dazzle the spectators. Randy Orton, on the other hand, will have a point to prove. And with Triple H keeping an eye on the proceedings personally, one should not be surprised if they see an appearance by Big Show during the match.
However, whether Big Show will follow Triple H’s orders or not, is another thing.
