Don't think anyone on the roster themselves is a draw. AEW is at the point where AEW itself as the brand is the draw and they got their core fan base, whether some people miss an episode or not, it seems they got a core group of people watching and that's it. It don't really seem to matter who is booked on the show and who is in the main event.
CM Punk might be the only guy that will bring in some extra viewership, but even then, he doesn't really bring in a ton of people, which was proven last year when he was drawing ratings in the 800k's.
AEW seems like it's at a point of "it is what it is" and unless there's another industry wide boom period like 1996, they're probably at a point of just trying to maintain what they have. As long as they keep making Warner Discovery happy and keep getting new contracts, their niche audience is probably enough for them.
