I voted yes, but it is not an unqualified yes. If the Cowboys didn't have the absurd contracts with Jaylon Smith, Demarcus Lawrence, Amari Cooper and Zeke Elliott, I would say 100% yes, sign him. But given their CAP situation, the best move for the future of the Cowboys may be to franchise him and then find a trade partner. I don't want to give up Dak, but they may have to considering how bad the defense is. They desperately need an infusion of talent there.
The problem is, if they let Dak go, what do they do for a QB? I am not one of those who thinks Garrett Gilbert is the answer, and DiNucci is at least 3 years away if he is ever good enough to win in the NFL. And taking one in the first round is still a risky proposition as so many teams have found out even in the last few years. Look at the 1st round QBs that have been relegated to backup roles, or their teams are moving on from them. Josh Rosen, Mitch Trubisky? Sam Darnold anyone?
It is a risk to trade Dak, but one they may have to take because signing him will leave nothing for the rest of the team - at least until 2022 when the Cowboys can get out from under some of the bad contracts they signed.
