I think the problem with what Cowherd is saying is that Dak isn't deserving of Russell Wilson money because he isn't as good as Russell Wilson. While Dak may not be as good as Russell Wilson all though he has beaten a Russell Wilson led team quite recently, the market has changed since Russell has gotten paid. Also most people can see that Dak has more good qualities than that of Kirk Cousins so that puts Dak somewhere in between. Dak has also been dealing with a coach fighting for his job on the way out and still put up some his best numbers. I can't put much stock in last year period but I can put stock in what Dak has shown in big moments and against good times many times in his career. Dak has balled out plenty of times in big games he didn't all of the sudden lose his abilities.
Again, the market has changed, and look at what first round picks get paid coming into the league these days and those guys might be total bust. Dak is simply a square peg getting jammed in a round hole. His situation is very unique, but it's my belief that many teams would be lining up to sign him for what he is asking or close. Guys like Cowherd get good ratings when they talk about the Cowboys and it's good entertainment to cause controversy. Despite whatever these guys say, Dak has proven he deserves to be paid top dollar at his position based on the intangibles that he is shown and that will play itself out whether you like it or not.
