Why would Dallas do that? Dak won more games as a starting quarterback than Cousins. Dak isn't elite, but he's a pretty good quarterback. Teams don't just let quarterbacks with Dak's numbers just walk out of the door with nobody to replace their production.
Dak, Peyton Manning, and Drew Brees all had one playoff win in their first 5 or 6 seasons. Matthew Stafford had zero playoff wins.... all of them were drafted higher than Dak, so if you would have released Dak after 5 years, then you definitely would have released Brees, Peyton Manning and Stafford who were ALL DRAFTED HIGHER than Dak, correct??
If not, that would seem a bit hypocritical, dont ya think?
