Shell Drill for Pack Line Defense

Jim Boylen, Head Coach of the Chicago Bulls, demonstrates the Shell Drill as it applies to a Pack Line defense. For purposes of a Pack defense, when coach Boylen talks of keeping the Shell in-tact, this is synonymous with keeping the Pack in-tact. Here he demonstrates correct help/gap position, correct open stance (Man-U-Ball), Stunting the driver, Closing out to the ball and closing out to Help (for off-ball defenders). This Shell Drill is run 3 on 3, but can also be run with 4 or 5 players per side.
