True, it was before Mahomes signed, but it is also true, as you said, we don't know how that will affect things. But that's irrelevant to the negotiation this year, and in the future, because we don't know yet, it really doesn't make sense to automatically assume he will demand Mahomes money.
If we play the season I would agree that France will advise that $35 million is outdated, and that's probably fair for him to do. But that doesn't mean he will require Mahomes money.
If we do not play the season, $35 million may still be a ballpark price because the league will be coming of a season with a lot of lost revenue. That is probably Dak's biggest enemy right now.
