JP's accuracy will improve with time playing the position. The more comfortable he feels back there, the more accurate his throws will become. There is no shortcut for developing a franchise QB. You just have to let him play and grow.
Kirwan is an idiot. JP hasn't had a chance to show his skills yet. A full year behind a better OL and we might have an idea. Probably two full years to be sure of what we got in JP.
