Then if it is about the future, you have to commit to a rebuild. My God. This team isn't young, and it definitely won't be in three years. If you get younger, you're probably going to get worse, especially if you are using premium draft capital on a quarterback.
And for the 100th time, the salary cap hit is greater, considerably, if you release Dak, rather than extend him. If you cut him, even as a June 1, you're paying him ~$25m, a rookie ~$4m, and a vet (i.e. Baker Mayfield) another ~$4m. You're talking about a cap hit over over $30m at QB, when Dak's with an extension at <$20m.
There is just no logic to anything you are saying.
