Isla Dawn, Blair Davenport, Authors Of Pain, Sonya Deville (WWE elected to not re-sign her), Cedrick Alexander, Giovanni Vinci of Imperium, & The Good Brothers (Luke Gallows & Carl Anderson).
WWE only signed Luke Gallows & Carl Anderson to keep AJ Styles happy.
I think WWE could've done more with Sonya Deville. She has a good catchphrase "Put your hair up & square up." She'll be a free agent at the end of this month. I think she'll do well on the independent scene.
Cedrick Alexander was in the Hurt Business. It is very likely that he'll be reuniting with The Hurt Syndicate in AEW.
