That's the point. France is going for the throat, with the assumption that Dallas has to re-sign Dak to compete. Jerry is throwing it back at him, essentially saying"prove it", knowing that the roster will be depleted. Will Dak look like a $60m QB while taking up $60m of cap space? Dak has struggled with lesser talent around him. 2022 was really bad, and they won in spite of QB play. How much value does Dak lose after a subpar season?
Jerry is essentially telling Dak to show him that he can win with less talent around him, and he will get the money he wants. If not, he can try his chances in free agency after a subpar season. He's finding leverage. If he's willing to ride it out, Dak's team loses leverage. The ball is in Dak's court.
