The chances of us being 6-2 with Rush and this receiving corps is extremely low. He has far too many limitations to elevate the offense to the point that we're consistently scoring enough to do that. IF it happens, it means our defense is one of the 2 or 3 best in football and we're consistently holding most teams to less than 20 points. Which admittedly is certainly within the realm of possibility, they've looked stout against 2 good offenses thus far.
But regardless, of course not. Dak is better than Cooper Rush in every conceivable way. Arm strength, accuracy, experience, mobility, knowledge of the offense, etc. Prescott is a top 10 QB, Cooper Rush is a run of the mill NFL backup QB. The fact that this thread exists is only an indictment of our fanbase.
