With it increasingly likely this Saudi show is gonna happen, can we stop the pretension and get Vince to go full troll, turning the horribly vague World Cup tournament into a literal Money in the Bank ladder match?
They can gimmick the case to fly open for the winner, spilling out stacks of hundreds, or Riyals for a local flavour (yes, that's flavour with a "u" my fellow Commonwealthian).
Better yet, put the performers appearance bonus in the briefcase ($2-3MM should cover it). Show up and they get to divvy up the cash after the match while Ted Dibiase's theme plays in the locker room.
THEY'LL MAKE MILLIONS!
Literally in this case.
