TNA/Impact Wrestling (and get used to that constant qualification...) hosted 12 LockDown supercards before permanently parking the concept in 2016.
For the uninitiated, LockDown was a supercard made up entirely of cage matches. Every single one a fracas fought inside the steel structure. It all happened because of a sarcastic put-down of the product at large.
Then on TNA’s creative team, Dusty Rhodes flippantly noted that the company should just go ahead and put every match in a steel cage one night. It was a caustic observation of a prevailing over-reliance on gimmicks in the industry during the post-boom mid-2000s. Nobody laughed, and the concept fit the organisation's desperation to subvert traditional expectations just to pull focus away from WWE as the industry standard. And so it came to pass.
There were some decent LockDown events in the years that followed, too. It was a concept too far - of course it was, you shouldn't repeat working a leg twice in one night, let alone a cage match - but it spoke to the complex near 20-year history of this strange pro wrestling company.
To this day there remains an enigmatic quality too much of the output. And unlike the vaunted McMahon Family lockbox, the secrets are out there and able to view. And where else to start than with the company's most infamous uncloseted skeleton...
