Wyatt has never done it for me in the ring, but I absolutely believe he's creative enough to make an AEW run work.
As for Punk, @cubbymark mentioned the possibility of him becoming one of the EVPs if he had signed two years. When was that ever on the table? I've never heard that. Jericho isn't an EVP. J.R. isn't an EVP. Even two years ago, I can't see an offer like that being made to Punk.
