No. The numbers that matter aren't about quantity, they are about productivity. TD percentage, completion percentage, etc.
I am not crediting Dak as the primary reason the Cowboys win or lose. I'm crediting Dak as the starting QB when they win or lose. That's because the primary function of a quarterback is to direct the offense in a way that they are efficient enough to win the game.
There are great passers and there are great quarteracks, they aren't necessarily the same. You don't have to be a great passer to find ways to get the ball into the hands of your playmakers, that's what great quarterbacks do.
I'm not saying Dak has been a great quarterback on a consistent basis but he far from being a poor quarterback on a consistent basis.
Again, Dak is not the issue. Hopefully we can agree that if the Cowboys had acquired a quality RB or if the defense was playing up to their potential, then this conversation would not be happening.
