I'm assuming they're trying to establish them now ready for those titles.
Not sure it was necessary though, off the top of my head you already have Jurassic Express, Best Friends + Orange Cassidy, The Bucks + Kenny, Dark Order, The Inner Circle (Guervara + Proud and Powerful), Some combination of Cody, Dustin + QT maybe?
I feel like The Lucha Bros should be babyfaces for a start. They always get a great reaction and their style of wrestling is anything but that of a heel.
Also feel like Pac should be in the heavyweight title picture and not mixed up in a trio.
