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.
