Another great [tag]basketball shooting drill[/tag]:“ the Partnered One-on-One Touch“ Drill.  I always use this one during high school basketball tryouts.

-“ Player 1 stands under the basket and Player 2 stands at the three point line in the corner

-“ Player 1 throws a chest pass to Player 2. 
-“ Player 2 catches the ball in the triple threat position as Player 1 runs out at him
-“ Player 1 touches Player 2 on the hip, and the two players play one-on-one
-“ Play continues until offense scores or defense rebounds.  Whoever scores or rebounds becomes the offensive player on the next possession
-“ The players move around the perimeter the three point line, starting the game at different intervals
-“ First player to nine points wins

Points of Emphasis
-“ Proper closeouts allow the defender to react quickly and change direction as the offensive player makes his move.  The defender should focus on shortening his strides as he gets closer to the offensive player.  His hands should come up to challenge the shot, and he should shift his balance slightly back as he gets closer
-“ Avoid lunging or leaping into the closeout, or the offensive player will blow right by you
-“ The triple threat position should be low, compact, and explosive, similar to a coiled snake.
-“ The jab step should short, quick, and hard, and no more than six to eight inches long. 
-“ Shot fakes should include the whole body, as well as the ball.  Bring the ball up to shooting position, while faking with the legs, shoulders, head and eyes.
