One of the [tag]basketball full court drills[/tag] that I find useful is what we call the 321 drill. It’s a full court drill that starts with 2 defenders at the far end of the court and 3 offensive players on the near court. 
The drill starts with a [tag]basketball coach[/tag] shooting from the free throw line. The 3 offensive players rebound the [tag]basketball[/tag] and start a 3 on 2 fastbreak. The 2 defenders must communicate who will “take ball” and then work to defend against numbers.
Whichever offensive player shoots the ball, he/she must then sprint/retreat back down to the near court and they now become a defensive player. The original 2 defenders have to rebound/gain control of the ball once the offense shoots and then those 2 defenders become offensive players and start and 2 on 1 fast break. The remaining 2 original offensive players stay down on the far court and will become defenders for the next group.
During the 2 on 1 break, once someone shoots, the next 3 players in line grab the rebound from this shot and take off down court, starting a new 3 on 2 break. This drill continues on like this until the coach decides its time to move on.
What’s nice about this [tag]basketball drill[/tag] is it involves fast, continuous motion and requires the players to communicate with each other. It also helps in conditioning the players since they’re running the length of the court.
