Steve Klaas – Dominating 1-3-1 Zone Defense

Reasons for running this defense:1. Put great pressure at the point of attack2. Stop strong post play3. Compete against superior talent

Positioning1 – Our best athlete, needs to be2,3 – Wings • 2 is usually smaller and quicker ° Lines up on the strongside • 3 is bigger and a good rebounder ° lines up on the weakside5 – Our big girl – always between ball and hoop.4 – Our baseline runner • Sprints corner to corner

In practice:• Always vs. 7 playersTeam Rules1. Every player must stay in a stance for the

entire position.2. Read the eyes of the passer.3. Move while the ball is in the air.4. Look to deflect

a. Turn your thumb down, and face your palm to the ball.

b. steals come from someone other than the deflector.

c. Mirror the ball (high/low)5. Everyone goes to the boards mad.

a. Our #1 never blocks out: he looks for caroms.

6. NEVER STOP TALKING

NCCP Level 3 Technical - Steve Klaas - 1-3-1 Zone Defense - 1

13: Slides – Quarter Court2 – meets and pressures the ball4 – slides to halfway between post and corner.1 – drops to the highpost area • has to stop ball reversal3 – drops to weakside lowpost area.5 – Stays between ball and basket at all times.* If weʼre playing good defense, weʼll always have 4 people on ballside.** forcing lobs allows defense to recover

When the ball goes to the corner:4 – pressures ballStrongside wing (2/3) – denies reversal5 – fronts low post1 – denies highpost

On corner to corner skip:• Wing high pressures, and forces baseline

(until bumped away or trap)• 4 still comes, and will get there for a

possible trap.• 5 needs to get around and front the new post

threat.

On corner to weakside guard skip:• weakside wing really needs to read eyes and

anticipate this pass.o Should be able to steal for easy

layup.• 1 is busy fronting the possible highpost

entry.


On the guard to corner skip:• wing breaks down on the high side to help 4

recover (then trap or bump back)• 1 should be in a position to deflect corner to

wing pass.

13: Adjustments - Penetration• penetration – need to stop great guard

o we want them to dribble the ballo help and recover

Drill Adjustment – Every player attempts to drive a gap.

Penetration through a trap• 5 goes to meet the ball (hands up)• 4 and weakside wing drop to the low post

spots (reading eyes)• 1 and strongside wing, recover deeper than

penetration

13: Adjustment – ScreensBall screens – there always needs to be help (if theyʼve got two, we do too).• we can either trap or bump off


Baseline screen against our 4• wing needs to be aware and help down

quickly• 4 battles around the screen and then bumps

wing up (or run Black)23: Halfcourt 1-3-1 (Base)1 – lines up at halfcourt5 – is at the top of the 3pt line• strongside wing meets the ball at halfcourt• 4 is a step off the lane• weakside wing has to make a decision

o read the weakside of the offense (stay at home or go for the reverse steal)

o

Breakdown Drill – Ball reversal/wing piston movement.On the guard to guard pass:2/3 – piston up and down4 – sprints short corner to short corner* add a guard to opposite corner skip and breakdown.

13: Adjustments – Extended/ShadowAgainst a team with a really good perimeter guard • When they pass the ball, we let the 1 delay

their slide and hang around (shadow) the star player.

o We also may have a “fire” call, so that every time the star touches the ball, we send a trap.


13: Fire• As soon as the ball crosses halfcourt, we

send the strongside wing and 1 to trap.• 4 lines up off the lane on the strongside.• 5 gets a hand in front of the middle release• weakside wing goes to the weak junction

area looking to shoot a gap (reading eyes).

13: Black – Corner Trap• As soon as the ball goes to the corner, we

trap.• 1 splits the highpost and the release pass.* If the ball goes to the release pass, 1 forces it back to where it came from.** If the ball goes highpost:

• 5 jams the highpost• 4 recovers to the hoop• 1 traps the ball.

13: Against Post Players• 1 stops worrying about ball reversal and

helps in the high post area.• 5 sags and battles strong side post.

13 Sluff – Against teams with 7ft at the top of the key.• if we canʼt dead front, or side front.• 5 plays behind, while the other players sag

(sluff) an extra step towards the post.


33: ¾ court • 1 lines up at the free throw line• 2/3 meets the ball at the hash mark

o weakside pistons back and forth (looking to pick off lazy skip)

• 5 plays behind middle entry• 4 goes sideline to sideline


12: 3-2 zone (almost like a 2-1-2)• When you donʼt have a 4 who can go corner

to corner.• wings meet the ball, while 1 drops to the

highpost areao almost inviting reversal

• On the pass to the corner, 4 goes to the corner and 5 comes all the way across.

12: Zone contOn the corner to corner skip or reverse.

• instead of one player sprinting sideline to sideline, 4 and 5 simply switch responsibilities.
