Dak is easily a constant top 10 QB, arguably top 5-6. If you put the right pieces in place, Dak can lead you far into the playoffs. Problem is Dak has gotten greedy, the team is in salary cap Hell, several younger key starters are due for their big contracts, the Oline, Dline and LBs are being rebuilt with draft picks and the WR crew and RB crew are still in need of another playmaker. Jerry knows if he allows Dak to leave via free agency, this team has no chance for the next 3+ years of making the playoffs and filling his stadium's seats. They young key starters know this as well. They will want to jump ship and try their luck elsewhere if Dak is gone, instead of sticking around and wasting their prime years with some much lesser QBs.
