That's actually a lot more than I thought, at least when based on the number of people who attended games in person.
As far as XFL 2.0, that wasn't really their fault. It was an unfortunate result of COVID hitting and shutting everything down indefinitely. Before that, they seemed to have everything going for them. They had managed to attract decent in-person attendance, a seemingly respectable fanbase, and their TV ratings were (if I recall correctly) relatively decent for a startup league. (I'm sure someone will correct me on the ratings.)
(AAF, on the other hand, was just bad product. Not the joke that was XFL 1.0, but just lousy football. Plus, IMO, the coverage really felt like the "brokered time deal" that I believe it was... everyone involved in the production seemed to be contractually obligated to laud the greatness of the AAF. It was kind of nauseating.)
