I've said it before, and will say it again.
The difference between Dak and someone like Cooper is that while Dak can get you more points, he turns the ball over more as well because he takes too many dumb, bonehead chances.
With Rush, they don't score as much, But the running and screen games are much better, The game overall is lower scoring because the defense stays off the field.
Dak loses 40-34 in games like these, while Cooper Rush wins 20-17.
Either way, neither of these QB1s will take us to the SB.
