1-3-1 Baseline Out of Bounds Defense in Basketball

1-3-1 Baseline Out of Bounds Defense in Basketball

The article was written by the University of Southern California Director of Scouting Martin Bahar.

 

The 1-3-1 Baseline Out of Bounds defense in basketball aims to eliminate easy layups and open shots by encouraging your opponents to try to lob the ball over the top of your zone towards half-court. The zone defense is packed in, and, ideally, your goal is to get teams to abandon their normal BOB strategies due to the fear of turning the ball over trying to inbound the ball against an unfamiliar defense.

Every member of this team basketball defense has a specific role that makes the defense work. This basketball coaching article will break down the different responsibilities that each player has in the 1-3-1 BOB defense. Here is a quick video breaking down Vanderbilt’s use of the 1-3-1 baseline out of bounds defense.

 

 

Vanderbilt’s 1-3-1 Baseline out of Bounds Defense

 

 

 

Man on the Ball (X4)

The man on the ball, usually your longest or most athletic player, is causing chaos for the inbounder. He MUST keep his hands up and active, jumping up and down to limit the inbounder’s vision and ability to find open gaps against the defense.

By putting a long, athletic defender on the ball, you hope to encourage the inbounder to lob the ball high in the air towards the backcourt, which will, hopefully, lead to steals and transition scoring opportunities the other way. X4 is trying to get deflections on EVERY inbounds pass.

If the ball is passed to the ball-side corner, the man on the ball (X4) and the ball side wing (X2) will trap the corner.

 

Big Protecting the Rim (X5)

Your five-man will sit on the ball side block, protecting the rim from any ball side slips, dives, and post touches. He must be alert so that no one can dive to the block for easy layups against the baseline out of bounds defense. Once the ball is inbounded, he must find the nearest offensive player to guard in case of 5 out situations.

 

Ball Side Wing (X2)

The ball-side wing is in an athletic stance preparing to close out on any ball-side corner passes. They must be alert and ready to not be screened in. If there aren’t any offensive players in the ball side corner, the X2 man can move in and help eliminate passes down the lane line. If the ball is passed to the ball side corner, the X4 and X2 will trap the corner.

 

Weak Side Block (X3)

The weak side wing’s responsibility is to take away weak side block/basket dives AND weak side corner passes. The hardest part of this job is when there is a weakside basket dive and a weak side corner shooter at the same time. In this scenario, you must protect the basket first and foremost, meaning take away the weak side dive to the rim.

 

Point Guard Just Inside the FT Line (X1)

Your point guard is usually the quickest player who plays the inbounds lob like a cornerback going for an interception. X1 takes ANY pass that is entered above the FT line. If there isn’t anybody above the FT line, X1 should move lower towards the basket or any vulnerable areas. On traps in the ball side corner, X1 should take the next pass out, usually towards the wing.

 

 

1-3-1 Baseline Out of Bounds Defense Conclusion

Remember in the 1-3-1 baseline out of bounds basketball defense; ANY DEEP PASSES INTO THE BACKCOURT IS A WIN FOR THE DEFENSE. Once the ball goes towards half-court, everybody must match up and find a man.

If you can eliminate the other team’s baseline out of bounds offensive sets, it could be the difference between winning and losing a close game. As a basketball coach, you are trying to get 6-8 points a game off of your own inbounds plays, so eliminating the other team’s baseline set plays can be a big boost to your defense.

  1. Smart way to force the lob. Great job explaining this and mapping out what each man’s responsibility is.

  2. I’ve coached basketball for a vast number of years, yet I never used a 1-3-1 defense against an underneath inbounds play. The explanation of Vanderbilts 1-3-1 defense against underneath inbounds plays was good stuff. I guess after all these years everyone that I talked to said it wouldn’t work. We have to think outside the box and be innovative. Anybody out there got any more innovative outside the box strategies against possibly sideline inbounds plays?
