I think 2K would need to assure the survival of the league first, like with 3+ years of sustainability. If it wasn't for COVID and the antics that occurred with the AAF's founder, maybe there is a chance that we would've already been in that place for any of these spring leagues. One can hope they stick around.
Of course, with a game in place, that would also have more people tune and in and watch it as well. It's a chicken-egg scenario, but I would absolutely buy it if they made one.
