Personally, I think they fumbled the whole MITB thing with Ziggler this year.
Wrestlemania is about a month away and he still has it. Why in the hell wouldn't he cash it in at Wrestlemania and announce it ahead of time so he could be in the 'main event' of the biggest show of the year? For the love of god, his moniker is 'The Show Off', what good reason would they have for him to NOT do it? So he could win the Tag Titles with Big E.?
Ok... but, why not compete for the tag titles and compete in the main event? Hell why not go for broke and go for as many titles as he could? He's THE SHOW OFF, his cockiness should get him in these impossible situations. I realize it would be insane booking to have him in a ton of matches but, there are always ways around that (triple threats, fatal four ways, etc...).
In kayfabe that is...
