Correct.l And basiclally, the labrum contributes to the stability (by containing the ball in the socket in suction cup-like fashion) and allows "smooth" movement of the shoulder, whille the totator cuff contributes to providiing full range of motor function and stability to the shoulder (by maintining even pressure of the ball to remain firmly in contact with the socket throughout range of motion). The "stability" is thus provided through different mechanism iby each entity.
