known? don't know.
i've long thought there are revenue caps at each level.
as an example, this season my team has greater attendance revenue than Upsyndrome, a team that is the reigning champ in both the Cup and league, currently in first place, and now in the Cup finals. that is nonsense, except A-Dubs has an enormous merchandise boost from his three NT players, my guess is his total revenue is not that much more than mine, considering the comparative quality of our teams. i think his attendance is limited to compensate for the flood of money he gets for the NT players.
