Cooper has aged and his already weak arm is now done. It's not compatible with an NFL attack.
Dak is Dak and should be out of the NFL by now.
Lance should get every snap the rest of the way. But he needs a offense similar to the 2016 involving alot of movement. If he fails we draft a QB.
IF he shows promise we trade out of the first and stockpile picks for next year incase he doesnt develop.
Dak can: Fight for his job and lose it or retire w/ injury settlement .
Unless Jerry is tanking in purpose, he needs to fire MM, promote Zimmer to interim HC, and let Shott OC slowly install plays for Lance.
