2 and X2 signify the respective offensive and defensive shooting guards.

3 and X3 denote the respective offensive and defensive small forwards.

4 and X4 designate the respective offensive and defensive power forwards.

What is an example of 1-3-1 zone offense featuring ball screen action?

This is an example of 1-3-1 zone offense that primarily features ball screens among other actions, ultimately to attack the 1-3-1 zone defense.

An example of ball screen action among other scoring options within 1-3-1 zone offense.

To begin, 1 dribbles into the gap of the zone near the left side high post area via the on-ball screen set by 4.

Moreover, while continuing that dribble action, 1 also utilizes another screen set by 3, which could potentially lead to a mid-range jump shot opportunity for 1 as well. Simultaneously, 2 drifts down toward the left side corner while 5 sets a screen on X1.

From there, 2 could receive the ball from 1 and take the three-point jump shot if that is feasible.

Additionally, after setting the screen, 5 could immediately duck in, pivot, and seal the backside defender, who in this case would be X3, via post up action.

From there, 5 could receive the ball from 1 via high low action and quickly score by way of a low post move prior to a 3-second violation occurring.

This quick hitting action could be quite effective as a possible defensive mismatch opportunity, particularly if 5 has a size advantage over the backside defender.

Furthermore as yet another possible scoring option, 4 could cut towards the extended right side wing area following the initial on-ball screen, receive the ball from 1 via skip pass, and take the three-point shot.

What’s also generally useful about this sequence as well, especially the gap attack towards the high post elbow is that if X4 commits very early during the initial screening action in an attempt to stop dribble penetration, then 2 could quickly receive the ball from 1, even before 2 drifts to the corner.

Additionally, if X3 is able to get through the screen near the basket and X5 drops back to protect the rim, then 1 would most likely have the mid-range jump shot opportunity as stated previously.

Once again, the offensive process and potential scoring options mainly depend on how the defense reacts to the ball.

What is an example of 1-3-1 zone offense featuring high post action?

This is an example of 1-3-1 zone offense that features action to get the ball into the high post area, ultimately to create scoring opportunities.

An example of 1-3-1 zone offense that focuses on getting the ball into the high post area.

To start, 2 receives the ball from 1 and immediately throws it back. This is mainly done to shift the zone defenders.

Afterwards, 3 receives the ball from 1. Next, 4 executes a flash cut from the left side low post area across the lane to the right side high post elbow area and then receives the ball from 3.

Following that, 2 drifts down towards the left side corner while 5 quickly ducks into the lane, attempting to seal the defender under the basket.

As that happens, 4 could look inside to execute the high low action with 5 as the recipient, which could lead to a close-range scoring opportunity around the basket.

Additionally, 4 could also throw a skip pass with 2 as the recipient, which could lead to a potential three-point shot opportunity.

What’s more, it should be noted that prior to 4 throwing the skip pass, if X5 were to drop back to protect the basket so that X3 could cover 2 in the left corner, then 4 could take the mid-range jump shot. In essence, 4 should have enough time to shoot before X2 is able to slide over to contest.

However, even if X2 were to slide over defensively to get in front of 4, then that means either 1 or 3 could be open for three-point shot opportunities, depending on how X1 or X2 would react to the ball.

Ultimately, 4 should read the defense and make the best decision given the circumstances.
