Good Idea #3: If AEW gets the upper hand, WWE will still save face
While some may criticize WWE's decision to pit its third-tier brand NXT against the upstart new kid on the block All Elite Wrestling, in reality, it's a brilliant strategy.
NXT, for most of its existence, has had no national television footprint. Only fans willing to subscribe to the WWE network were able to catch the thrilling escapades of the Undisputed Era, Velveteen Dream, and Matt Riddle.
This means that by putting NXT on the USA Network, WWE will have already scored a significant victory for the brand by expanding its audience beyond subscribers.
Also, even if AEW manages to defeat NXT in the ratings war, temporarily or otherwise, the WWE hasn't really lost much. The perception will be that the 'main' brands of Raw and Smackdown haven't been defeated in the ratings game, just their developmental brand.
And if NXT comes out on top of the ratings war, temporarily or otherwise, then WWE can point out that even their third-tier brand is superior to what AEW has to offer.
Either way, it's a win-win situation for the WWE and the NXT brand.
