Not a Good Idea #2: WWE isn't bringing their A-game to the fight
If WWE wishes to go head to head with All Elite Wrestling, then why would they use their third-tier brand as their opening salvo?
NXT fans are rabid and dedicated, and both wrestling critics and the internet wrestling community are very much invested in their product. However, NXT is WWE least profitable brand, although admittedly much of this has to do with the Yellow Brand not having a national television audience.
Perhaps WWE would be better suited pitting their major stars, such as Roman Reigns and AJ Styles against the counter-programming AEW has to offer? Instead of relying on promising but unproven talent, they could bring their established wrestlers to the fight.
By committing their third-tier product, WWE might be making a mistake.
