As they shouldn't, he hasn't earned it. He took a dump on the face of the best talent on the roster and said "fuck you, I don't have to do SHIT but show up and pin you after you carry the entire program". Disrespect begets disrespect. Undertaker is a selfish, arrogant, broken down old has been who can't give it up, who doesn't give one shit about the next generation of stars and helping the company that made him thrive. It's always all about him.
Show just needs to retire. Some people put wrinkles in their career for staying active a little too long. Show is already there imo.
I really hate Sheamus, but dropping the belt to Show must not happen. We'll end up having an extended Show/Sheamus feud that will be boring and uninteresting. If Sheamus drops it to show, it's probably b/c Ziggler is about to successfully cash in.
One might hope that the long game will be Barrett v. Sheamus feuding, leading to a Barrett WHC reign and a face turn for Ziggler post MitB cash-in. Barrett and Ziggler can both talk, and should be reasonably entertaining.
And no Big Show in the title picture, because reasons.
