Wentz didn't shatter the qb market with his deal. He could have conceivably held out and topped Wilson, Rodgers and Worthlisberger's deals, but he didn't. So that's good for our 'Boys.
On the other hand, there is no chance Dak takes less than Wentz when it comes to his contract. Wentz has played at an MVP level for stretches, but Dak won Offensive Rookie of the Year and has never missed a game. He's won multiple division titles for the Cowboys. That matters. Also mattering? Dak IMO has been severely underpaid thus far in his career relative to Wentz.
Spending the first three/four years of his deal on a 4th round rookie salary will likely incentivize Dak to make as much money as he can on his next contract, especially considering his age 26, meaning he might get just two full length deals, although considering how the Cowboys operate he'll probably sign 13 extensions between now and 2025.
Getcha popcorn ready, Jerry will pay his boy more than Wentz. It may always be sunny in Philadelphia, but things are always bigger in Texas.
