I agree that you need vets. However, if the vets aren’t clearly better than the younger players, you play the younger guys. At minimum, you split the reps. As someone, who personally entered P4 as a freshman and immediately contributed at a high level, I know firsthand that it isn’t impossible.
Realistically, the way our team is built we should be a run first operation this year. Beck is coming off injuries and, we have a young receiving core. Our Oline is built to overpower teams. Run the ball and build the passing attack over the course of the season.
