Aaron Franklin is running a restaurant and is cooking probably 70 or 80 briskets a day! I will almost guarantee you that his rub doesn't get too much more intricate than salt and pepper! He may throw more stuff on at home or for small batch cooks but I doubt that he does when cooking for the masses.
