I need multiple receivers that can get consistent separation, extra OL, a star RB, and a top 10 defense to have Prescott compete for a Lombardi. He is not good enough to make up for holes in the roster particularly in high pressure games like the playoffs.
After 8 years we have a sufficient sample size to say he is what he is and he is only going to get worse as he progresses through his 30s.
Now way on Earth he should make more than $40M. I would rather have a Gino Smith, Kirk Cousins, Jared Goff, significantly cheaper if marginally less talented option to build a super team for than watch Dak continue to fail. I would rather tank.
The QB FA market is disgustingly inefficient. That does not mean you double down on it where the inefficiency is worst. Signing Prescott to $60M AAV is precisely that.
