The guy should of retired a long time ago. It would be a disaster. Have Sheamus say to him that if he loses at TLC he's officially gone. It is the only way I would want to see Sheamus as Champion again. Anything as long as Show retires as soon as possible.
I'm with everybody in the 'no' category. Ziggler should be holding the belt right now because it does absolutely nothing for Show as he was strapped just so Sheamus wouldn't look weak. The WHC has become the measuring stick for guys that are new to the main event so I don't see the point in an old vet carrying it for any extended period of time.
He'll retire as a face and right now he's in full cowardly heel swing - he'll drop the belt soon and either disappear for a while and come back as a face, or he'll just turn face when he loses the belt.
