re: Assuming that Jalen is QB1 going into this season, how do you help him?

To start, good snaps that will allow him the opportunity to even have a chance at making the proper read. Then solid protection from the OL from the opening snap of Game 1. Give him High/Low reads. Split the field in halves or even thirds. The first two will go a long way in to how successful he will be and how successful this team can be this fall.
