More discipline from the arc

Once again last year we had too many people shooting 3's who were not hitting 3's. We seemed to have become much more disciplined in our shooting for a while, and then last year it fell backward. There were some reasonable explanations. First was Will Neighbour's frustrating and unexpected shooting collapse. Second was the fact that we had so many new faces that we did not know who would be the good shooters. But we should be able to designate the shooters this season, and so we ought to be much better from the arc.
