I think your first point and fourth point are in conflict with one another. I think EJ has to get Hackett's confidence in the red zone, then they'll open up the playbook. Today, despite the frustration of it, I get why they were conservative. They were moving the ball up and down the field on a team that their defense was absolutely dominating (64 yards without getting into Bills territory in the first half). Instead of doing something that was going to get them burned, they relied on their running game and came away with points. There is also something to be said about being able to run when a team knows it's coming, and if this is the way they're going to bring EJ along, then they've got to be able to do that, as well.
