As we saw on last night’s Money in the Bank PPV, The Miz interfered during the Intercontinental Title match between Ryback & Big Show.
This led to Big Show winning the match via DQ & hence Ryback retained the IC title. The interference was done to set up a triple threat match between them at the next PPV, WWE Battleground 2015.
This triple threat title match was originally planned for the Money in the Bank but those plans were dropped, apparently because of lack of direction for mid-card wrestlers.
They probably just want to fill up the PPV card as 90% fans watch on WWE Network & nobody has to pay $50-60 nowadays.
