So, Ziggler has been Mr. MITB for quite some time now and hasn't cashed his briefcase in yet, and he can only cash it in on the WHC, who is Sheamus. He'll defend the title against Big Show at HIAC. Ziggler has until next year's MITB PPV to cash in. Given the facts, starting from now, when would make him cash in, and how? Hypothetical situations with new champs and such are allowed ofc.
