#4 CM Punk has already named AEW opponents he wishes to face
CM Punk was asked by a fan on Twitter about AEW opponents that he wishes to take on if he does return to the ring again someday. Phil Brooks gave the rub to Will Hobbs, Darby Allin, Brian Pillman Jr., Ricky Starks, and Jungle Boy.
If you tease something on the internet, the internet blows up! CM Punk could certainly show up at AEW and have all of these matches (and more!). The possibilities are limitless.
#3 Far more creative control
One has to believe that if CM Punk does come back to pro wrestling in any kind of capacity, he will exercise a certain amount of creative control.
That said, there's one man who rules WWE with an iron fist. It may be easier to do business in an environment like All Elite Wrestling, which is run by someone who's likely to give Punk far more creative freedom.
As we've heard from creative guys like Malakai Black, they like to prosper in an environment where the shackles are off.
