The backboard has inbounds status, therefore, so does the rim. If it has status with regard to inbounds/out of bounds, it must also have status with regard to inside/outside the line.

4-4-5: A ball which touches the front faces or edges of the backboard is treated the same as touching the floor inbounds.
