I don't care, and I think the importance of it is overblown. I understand the cowboys hesitation on players like Prescott, or when Philly had Foles, and Washington when they had Cousins. They weren't that highly rated coming out of college and the clubs are just weary of overpaying for guys that scouts didn't think that highly of. It's like every game for these players is "the real test".
Prescott has outplayed his contract, but will he get better, or have we seen the best of him already? In the biggest question is do you think he could win a Super Bowl the way he is? The FO needs to answer those questions, crap, or get off the pot with Prescott.
If they decide on signing Dak the most replaceable star is Cooper. Ezekiel is not as easily replaced so I would sign him and wave goodbye to Cooper.
