So hypothetically AEW would have Punk/Bryan/Cole/Bray/Andrade/Black/Miro/Cody/Jericho/PAC/Christian on top of their non WWE acts who are over like Omega/Darby/Page/MJF/Sammy/Bucks/Cassidy etc not even mentioning the rest of their roster and they're gonna have to fit into 3 hours of TV programming and im supposed to believe nobody will be the odd man out and everybody will be booked to perfection
Everyone you named has other wrestling promotions or other jobs that will have them in and out of AEW. In WWE, if you aren’t used, you have to be backstage in catering. Well Andrade may be in Mexico for a while, Black may do Europe for a while. Mox, Bryan, Jericho will be in NJPW, and so on.
