Drill- Pressure The Shot

....playing great on-ball defense, and also getting a hand up on shots (to put additional pressure on the offensive player).

Start in one corner of the court (where the sideline meets the baseline), in a good defensive stance, and slide quickly and powerfully to the elbow (where the free throw line meets the corner of the lane). As you get to the elbow, imagine that the player you are guarding is going up for a jump shot. So as you near the elbow, gather yourself and leap up to block the shot. After you come down from your jump, turn to block out the shooter. Do this drill five times from each side of the court.

There will be lots of times where you have to quickly transition from a defensive slide to a jump (either to block a shot or grab a rebound). So practicing this will translate into being a better defender in game situations.
