I think after 7 years in the league, one would tend to think that Dak has maximized his upside. He has had the benefit of having a solid supporting cast over the years along with the continuity of being in the same offensive system. I don’t think he is a bad QB; I think he gets scrutinized because he plays for the Cowboys and makes $40MM per year.
I think he is a great leader, but he has issues with his consistency of play, passing accuracy and reading defenses; and to a lesser extent, I think injuries have limited his mobility and he seems less keen to run with the ball. At this point…I think he is what he has shown us he is; a competent QB that will lead an offense able to generate enough points to lead the NFL, but unable to lead that same offense to a post-season victory.
As another poster mentioned, I would be curious to see how Dak would function in another system.
