#2 Jon Moxley
This wrestler is a double champ. He is currently the IWGP United States Heavyweight Champion and the current AEW World Champion.
Jon Moxley is undeniably a box office draw as he leads the company in racking up head-to-head victories in the Wednesday Night Wars against NXT. The Purveyor of Violence takes the second spot as he is one of the best and most popular wrestlers in the world right now.
After leaving WWE, he immediately became a star in the indies and other promotions as he was one of the most highly sought wrestlers, and his wave of popularity remains high even to this day. The former Shield member went back to his old persona and came to AEW, and the company did an incredible job on presenting Moxley as a legit main-eventer.
Now, he's currently feuding with Brian Cage and they have a scheduled match at Fyter Fest. It'll be unsurprising when he retains since his time on top is surely not yet over.
With a lot of tremendous matches and big accomplishments this year under his name, Moxley is certainly deserving of the No.2 spot.
The former Dean Ambrose maybe the wrestler that AEW will be pinning their hopes on to help the promotion grow.
