Signing Dak to a 40 million per year contract is a horrific idea. If your goal is to go between 7-9 an md 9-7 than sign him up. The Cowboys need to be smart and realize we already got the best years of Dak. Very competent QB play and paid him practically nothing his first 4 years and a high salary this year. Sign a cheaper option at QB, preferably a draft pick. Or even Winston as crazy as that might sound he led the league in passing. There have been more crazy ideas that worked. No one that Tannehill was any good.
Dak is a slightly better or equivalent to Goff, Wentz, Cousins
