I'm thinking Colin is correct in saying it's tough to evaluate Dak at this point in time!
It does seem to be the underlying cause of these negotiations being at an impasse.
According to the leaks, it's about the Cowboys wanting a longer term deal than Prescott so they seem to want him more than he wants them, especially in the long term.
He said coming in that being the DC QB was a lifelong dream of his but now he has realized that dream. They all know the likelihood of remaining with one team for their entire career.
The other thing we do not know is how does he truly feel about the organization? If he were a QB for any other team in the league, there would not be this level of coverage and there have been some leaks, by design, that have been made to look him look greedy. Has anyone considered that his reluctance to anything beyond 4 years might not be only money related.
Consider this. What if Prescott sees the future of the team when Booger is gone and doesn't like what he sees? Booger will be 81 or 82 when this 4 year deal is up. Maybe Prescott wants options and tagging a QB in 2024 is going to be prohibitive?
One thing we do know. A lot of players come into the league with favored teams they'd like to play for but once they're in for a couple of years, it's all about who will pay the most guaranteed money.
I do believe Prescott is a top 10 QB right now but in 4 years? The competition seems to be heating up as evidenced by the poor FA market for QB's this off season.
