#2 Needs Improvement: The heat machine known as Orange Cassidy
In the modern pro wrestling world, there's enough interest and fan knowledge that you're starting to see 'meta-wrestling' gimmicks.
Meta wrestling, simply put, is a gimmick centered around certain aspects of the business itself. It's not a new concept, but one that has grown more popular. During the Attitude Era, DX claiming they wanted to get fired so they could join their friends 'down south' was a meta wrestling gimmick, because it required real world knowledge of the contractual situations of DX's friends Scott Hall and Kevin Nash, and the infamous 'curtain call' incident.
But the most meta of all meta wrestling gimmicks has to be Orange Cassidy. In an industry dominated by apoplectic posturing and over the top shenanigans, Freshly Squeezed Orange Cassidy stands out by being the exact opposite; Unenthusiastic, lazy, and almost bored in his execution of all moves, including diving over the top rope. In fact, he seldom bothers to take his hands out of his pockets at all.
Orange Cassidy is over with a capital "O," but AEW seems intent upon keeping him as a sidekick to the Best Friends. This could be changing with a possible feud against Pac, but AEW could be squandering an opportunity to create wrestling's next big star.
