The Dallas Cowboys view Dak Prescott as their franchise quarterback. They have made that known in these recent contract negotiations and there is no reason to believe that Prescott won’t be QB1 for the Cowboys for a very long time. Yes, the current contract negotiations are not going as smoothly as hoped, but there is belief all around that they will get done.
In the current Cowboys history timeline, Kellen Moore breaks his leg in 2016, then Tony Romo gets hurt in preseason, forcing the Cowboys to turn to a fourth-round draft pick they had just selected that April, a guy named Dak Prescott.
