How clueless is he?
Dynamite is doing 2k for some shows now, how fucking much does he think Dark would draw? Tv tapings alone cost more than they bring in from the gate, and house shows will lose a lot more money and they'd either have to use jobbers and unknown people, or pack it with their top people to try and draw, and the top people will renegotiate their contracts due to the increased workload, plus you have more injuries and less people for tv. There's literally no benefit for AEW here.
