4-40-3: "...from the front or side (within the visual field)..."
4-40-4: "...from behind (outside the visual field)..."
Is a screen from the side ALWAYS considered "within the visual field"?
Can a legal screen ever be from the side but "outside the visual field"?
Application: A screen is set just short of contact on a player's right side while that screened player's head is looking to her left. Legal or illegal?
