This is a drill that Brad Stevens uses to practice his transition defense. The goals for the drill are to stay in front of the ball, protect the basket, pick up the ball and find the shooters.
This is the initial setup since it simulates a game situation.
x1 shoots a free throw. Place 1 and 4 near or on the free throw lane.
Make or miss, you can play from there.
As soon as the coach indicates the drill starts, x5, x2 and x3 sprint back to protect basket.
After 4 passes to 1, 1 slides over to stay in front of the ball-handler.
x4 drops back to around mid-court.
x4 will provide help to x1 if the ball-handler is able to blow by x1.
If x1 contains 1, x4 will pick up 4 as they head down the floor.
After 4 passes the ball to 1, 4 will clear the area to give 1 room to bring the ball up the floor.
At times, 4 can also set a ball screen to relieve pressure.
x1 is just giving 1 token pressure. If 1 basically hands the defender the ball, x1 should take it. Otherwise, x1 should coast along with ball handler.
x3 can play up the line to help stop the ball if necessary but also be in position to recover to shooter 3.
x5 needs to be in position to stop dribble penetration, help baseline, and also prevent a lob to x5.
X2 is to provide help defense but still needs to be able to get back to shooter.
If the drill is ran as intended with x1 staying in front of 1, here is where the offense will be.
You can play the way you want from here but I like to get into the ball-handler and have the other guys play the gaps, though there are times that I would play one man off the ball straight up (based on your personnel and your opponents' personnel).
x2 may slide over to left lane line but that depends on your personnel.
Run and Jump Variation
Here's one variation to the drill, particularly if you like to run and jump.
After 4 passes to 1. x1 slides over to play 1 straight up.
X4 drops back to mid-court and mills around there.
x3 and x5 drop all the way back to protect the basket.
x2 can drop back a little but is basically the center fielder. You want x2 to move towards mid-court.
x1 gets into 1 so much that the ball-handler feels uncomfortable. x1 shades to the middle.
4 will head down the court after passing the ball.
As soon as 1 puts the ball down on the floor, 4 runs and jumps at 1x. The double team remains as long as the trap is still in play.
2 picks up 4 and tries to deny/prevent the pass to go to 4.
x3 and x5 then guard the other three players.
Once the trap is broken, x4 needs to hustle back down the court to pickup the open man.
