Take a look at these submissions from John.  A great example of a [tag]basketball zone defense[/tag] [tag]coaching[/tag] tip and a [tag]conditioning[/tag] [tag]drill[/tag] that can work with all age groups.Basketball Zone Defense

From John…
Here is a drill I love and a simple coaching tip–

Quick coaching tip:

Next time you are up by 1 or 2 points and the other team has the ball at the end and calls time out to set up a play, switch your man-to-man defense to zone or vise versa.  Another [tag]coach[/tag] did this to our team and my kids freaked out and couldn’t adjust (we didn’t have another time-out).  I’ve tried it twice to other teams and it worked both times.

Here is a drill I love:

Fun [tag]basketball[/tag] drill for conditioning while working on some fundamentals:
Players line up at half court on the sidline.
One player steps out as a point guard (player A).
The next player (player B) [tag]sprints[/tag] to the basket, receives a pass from player A and shoots a lay-up.
Player A waits until the ball is rebounded and then takes off down the court.  Player B [tag]rebounds[/tag] his own ball and takes it out. He must clear the board and throw a baseball pass to Player A.  He then must sprint the court and grab the rebound before it hits the floor.  He then takes it out again, clearing the board, and throws a pass to the next player in line who is shouting “outlet” and calling for the ball with their hands and coming to the ball. Repeat again and again.
