You don't mention if the cable is clamped in the box, or if it is a single gang NM box. If a single gang nonmetallic box without a clamp then the lencth of the cable, measured along the cable to a point where it is secured cannot be more than 8 inches (314.17(C)exception. I have seen cables stapled within six inches of the box with an additional 12 inch loop before it went into the box. That made it a violation. Alan
