You really can't blame AEW with how Punk's used because Punk is doing exactly what he wants to do. Wrestling midcarders, doing occasional commentary and "happy to be here" is exactly what he wants. The latter is going thin with me admittedly as I want him to start working proper feuds with people.
AEW is building up Miro again after losing the TNT title so he would be great for Punk's for major feud and/or loss.
