Sideline Out of Bounds Plays: Complete Playbook
Sideline out of bounds plays are the most undercoached dead-ball situation in basketball. Run them right and you manufacture clean looks from nothing. Run them wrong and you hand the defense a free stop.
Why SLOBs Are Different from BLOBs
Most coaches treat baseline out of bounds (BLOB) and sideline out of bounds (SLOB) sets interchangeably. They share vocabulary — stack, box, line, screen-the-screener — but the court geometry is completely different, and that changes every design decision you make.
On a BLOB, your offense is crowded under the rim. You have five players in a tight zone, the inbounder is stuck out of bounds, and your best options are lobs, post entries, and quick layup cuts. There is no room to work and nowhere to flow.
On a SLOB, you have open court. The basket is 15 to 28 feet away depending on where the call is made. The inbounder re-enters freely after the pass — becoming a fifth live option on the very next action. And you can flow directly into your half-court offense without resetting.
That last point matters more than coaches realize. A SLOB doesn't have to be a one-shot play. It can be a deliberate on-ramp to your pick-and-roll continuity, your dribble-handoff chain, or even your base motion. The offense controls the spot, controls the start time, and controls who re-enters and where. No other dead-ball situation gives you this much leverage.
The SLOB is also the most natural after-timeout vehicle in basketball. You call time, draw it up, set it in motion. Every detail is in your hands before the ref hands over the ball.
The Two-Phase Structure Every SLOB Needs
The most common SLOB failure at the high school level is simple: one decoy, one cutter, and if the cutter is covered, it's a jump ball. There is no recovery plan. Olympic-level SLOB design — specifically the framework used in the 2024 Paris Olympics sets — builds every play around two sequential phases, not one.
Phase 1 gets the ball inbounds safely. This is not the scoring action. This is a screen-the-screener sequence or a quick flash that pulls a help defender into rotation and creates defensive commitment.
Phase 2 is the scoring action. Because the defense shifted in Phase 1, it now has to recover. That recovery window is where your play lives — a dribble-handoff leading into a slip, a ball screen opening a drive lane, a stagger freeing your shooter, or a back-cut to the rim.
A SLOB that tries to score on the first pass is a SLOB with no second option. Design two phases and you always have a read. Even if Phase 2 doesn't produce a shot, the inbounder has re-entered and your offense is already running.
The SLOB is the most natural after-timeout vehicle in basketball because the offense controls the spot, controls the start time, and re-enters the inbounder cleanly — making it a five-player action from the second pass forward, not just the first.

SLOB Alignment Families Explained
The same five alignment families that organize BLOB sets apply to SLOBs — but they behave differently when the court is wider and the basket is farther away. Here is how each one translates to the sideline.
Stack SLOB
Two or more players stacked tight on the ball side, peeling toward the basket or to the wing. The key is sequencing: the first player out is the decoy, the second cutting under or through is the primary. The Alabama Stack Backdoor (2024 NCAA Bracket Busters) is the cleanest example — Player 1 dribbles toward Player 3, selling a dribble-handoff. Player 3 reads the defender's commitment and cuts backdoor immediately. The handoff never happens. The defender's reaction to it is the entire play.
Box SLOB
Four players in a box near the sideline. The wider court creates better cutting angles than a baseline Box set. You can run a stagger for a shooter (toward the basket) or a back screen for a lob (corner depth). The Spurs EOG Triple SLOB is box-origin: three screeners in sequence free one shooter for a catch-and-shoot 3-pointer. Clean and accountable — every player has one job.
1-4 High SLOB
Four players spread across the elbow/wing line with one at the top. This clears a lane to the basket and sets up natural PnR and lob actions because the floor is empty when the action begins. The Jay Wright Late Game SLOB starts in a spread 1-4 look: the big dives to the rim, a wing sprints to the elbow and immediately back-screens the shooter for a lob. Counter built in — if the inbound is denied, the inbounder's back-cut opens as the default read.
Line SLOB
All five players strung in a line along the sideline, creating simultaneous multiple-cut opportunities. This is the most read-heavy alignment — Hubie Brown's "10 Seconds or Less" SLOB is a five-read flow chart where each option is live for only a moment before the next one opens. Worth installing for advanced groups; too many moving parts for a team that hasn't repped it heavily.
Spread / Wide SLOB
Players spread wide, clearing space for a 2-man action or isolation. The Northwestern Wide Horns Slip spreads the floor and runs a flare screen — but the actual scoring action is the slip from the screener before the defense recovers. The spread is the decoy setup; the slip is what you're running.
Man-to-Man Counters and Misdirection
Every effective SLOB against man-to-man defense shares the same core logic: manufacture an overplay with a believable first action, then exploit the defender's commitment. The mechanism changes; the principle doesn't.
DHO Fake to Backdoor
The single most productive SLOB action across multiple playbook sources. The defense has to honor the dribble-handoff threat — they can't sag off or you complete it for a catch near the basket. The moment the defender commits to the DHO, the cutter goes backdoor. The Alabama Stack Backdoor, the Albany Women SLOB, and the Yale Zoom all use this exact trigger. The cutter is reading the defender's head, not the diagram.
Screen-the-Screener
The player who sets a down screen or back screen to free the inbound catcher is immediately screened by a third player as the ball is in the air. The defender who hedged on the first screen is now getting screened themselves. This is the dominant action at the Olympic level and appears in Tigers 1 (Sideout 8): Player 1 comes off a downscreen combined with a back screen for Player 3 — two layers, one sequence.
Inbounder Back-Cut
After any SLOB inbound, the inbounder's defender relaxes. It is a habit so deeply ingrained that it is almost universal. A taught inbounder cuts hard backdoor the moment the ball leaves their hands — the defender is still standing in their inbound stance, frozen. This is not a called play. It is a discipline. The Albany Women SLOB (from the Hackenberg backdoor library) isolates this exact mechanic: the inbounder rip-cuts immediately after releasing the pass and scores the majority of the time because no one guards them.
Slip Off the Screen
The screener sets a flare or down screen, reads the defender over-hedging, and slips early to the basket before the screen is fully set. The Colorado SLOB Rip Iso is built entirely around this: Player 1 sets a back screen for Player 5, then flashes to the ball. The screen was the decoy; Player 1 receiving and attacking in isolation is the play. When your screener is also a capable ball-handler, this becomes one of the hardest actions to guard.
Beating Zone Defense on SLOBs
Zone defenses on SLOBs typically station a guard near the inbounder to deny easy passes into the gaps. The approach most coaches take — throwing the ball into the corner and hoping — is exactly what the zone is designed to allow. The ball ends up on the perimeter, the offense resets, and the zone has done its job.
The counters are more deliberate.
Flash to the Middle Seam First
The highest-percentage zone entry on a SLOB is a ball-side big flashing hard to the mid-post or elbow. Catch the inbound there, and the zone has an immediate problem: it cannot simultaneously cover the middle and the perimeter. Sideout 4 from the BLOBs Playbook is built on this — the big flashes, receives, and immediately feeds a cutter for a layup. The zone cannot defend both at the same time. This one action breaks most zone SLOB defense in one pass.
Quick Reversal to Attack Weak Side
If the zone slides hard toward the first pass, immediately reverse the ball. Zones cannot recover across the lane in a single step. Michigan's zone end-of-game set isolates this: a free-throw-line cut occupies the top zone defender, a back screen frees a lob cutter on the backside after the reversal, and the weak-side player is completely uncovered. One skip pass and the play is live.
Two Cutters on Adjacent Zone Seams
Flood two adjacent zone seams simultaneously. The middle defender must pick one. A skip-then-cut sequence is the simplest version: skip to the corner (one zone defender chases), cut from the weak side as the middle defender commits (one zone defender shifts), and the cutter arrives alone. This is the same seam-flooding principle used in zone BLOBs — two bodies in adjacent gaps are always one more than the zone can cover.
Against zone on a SLOB, the temptation is to hold and wait for an opening. Resist it. Zone defenses get more organized the longer they sit — they rotate, they communicate, they lock in gaps. Attack within the first two passes. Your best window against zone is the first three seconds after the ball is inbounded, before the zone's off-ball defenders have fully recovered their positions and communication is established.
End-of-Game SLOB Specials
When a SLOB occurs near half-court in the final seconds of a half, the design logic shifts entirely. You are no longer looking for a layup or a mid-range shot. The scoring window is a 3-pointer off a single clean screen, and the ball must travel from the inbounder to the shooter in one pass — any extra touch gives the defense a rotation step.
The key rules for near-half-court SLOBs:
- The ball must get to the shooter in one pass. No relay passes, no extra touches.
- The screen must be set on the ball side. A counter-side screen with a skip pass takes too long — the clock wins.
- The shooter must catch in rhythm. One extra dribble gives the defense a recovery step and the shot becomes contested.
The "2 Pop" SLOB
Player 5 back-screens for the shooter, who comes off a staggered down screen from Players 4 and 3. One clean 3-point catch-and-shoot. Two layers of screening, one receiver, one pass. This is the purest end-of-game quick-3 template — straightforward to install and hard to stop when the screens are set with physicality.
Spurs EOG 3 Quick Hitter
Player 1 relocates to the corner as a decoy and spacer. Player 4 screens for Player 5, then Player 5 screens for Player 3, who cuts to the top of the key for the catch from the inbounder (Player 2). Three bodies, one clear receiver at the top, one pass to a 3-point catch-and-shoot. The chain of screens takes roughly three seconds — appropriate when you're down 3 with five to eight seconds remaining. The Spurs attribution also earns automatic player buy-in.
Jay Wright Late Game SLOB
Starts in a spread 1-4 look. The big dives to the rim (Phase 1), the wing sprints to the elbow and back-screens the shooter for a lob (Phase 2). Counter built in: if the inbound is denied, the inbounder's back-cut opens as the immediate alternative. Two-phase structure, one inbound, two looks. Clean enough to rep in a single walk-through before it goes live in a game.
Four Plays Worth Installing Right Now
Coaches often build SLOB menus that are too long. Here are four plays — one quick-hitter, one backdoor set, one two-phase flow play, and one zone-buster — that cover the situations you actually face in games.
Alabama Stack Backdoor
Stack alignment. Player 1 dribbles toward Player 3, selling the dribble-handoff. Player 3 reads the defender's commitment and cuts backdoor immediately. Primary read is the backdoor; the DHO never happens. If the defender sags off and ignores the DHO threat, complete it for a catch near the basket — that's the built-in counter. One alignment, one trigger, one read. Teachable in 15 minutes. The quickest-install SLOB in any playbook and effective against any man-to-man defense that over-guards the handoff.
Detroit X Play (Sideout 7)
Player 5 downscreens Player 1 for a corner 3 (primary). If blocked, Player 2 runs off a Players 4/3 stagger for a wing 3 (secondary). Two shooter reads, zero dribbles, both are catch-and-shoot. Ideal for teams with two reliable perimeter shooters — the defense literally cannot cover both cuts with man-to-man principles. FCP's standard go-to SLOB for shooter-heavy lineups.
Tigers 2 (Sideout 9)
After the ball is inbounded, Players 1 and 5 run a pick-and-roll. If Player 5 isn't open rolling, kick to Player 2 for the 3 or wait for Player 5's post seal. This is a deliberate SLOB-to-half-court flow set — the play doesn't demand a quick shot. It uses the SLOB alignment to set up a favorable PnR situation and lets the offense read the defense's choice. Best used when the defense sells out to deny the initial inbound action and the offense has already secured the ball safely.
Spurs EOG Triple (Box)
Box alignment. Three screeners in sequence free one shooter for a catch-and-shoot 3-pointer. Every player has exactly one job. Attributed to the Spurs, which means players execute it with confidence rather than skepticism. Install this as the designated "down 3 with under 8 seconds" SLOB — answer the "2 or 3?" question first, then call the play if the answer is 3. Rep it in late-game practice scenarios until the chain of screens is automatic.
Timing Discipline: The Jay Wright Rule
The biggest SLOB mistake at the high school level costs zero possessions in practice and multiple possessions in games. Players take the ball from the referee before every player is in their spot. One player still walking to position destroys the manufactured deception in Phase 1 before the play begins.
Jay Wright's design note from the Game Winning Specials Playbook makes this operational: the inbounder "should take his time and act busy (tie shoes…) before taking the ball from the ref." The value is twofold. Every player is set before the play starts. And the acting-busy routine is its own decoy — the defense watches the inbounder fidget instead of reading the cutters' positioning.
This rule costs nothing to install. The SOP is simple: the inbounder does not call for the ball until all four other players have made eye contact and signaled their spot. Players who don't know the rule lose possessions at exactly the moments that matter most — late in halves, late in close games, during ATO sets where the defense is already locked in.
Pair the shoe-tie rule with the inbounder back-cut discipline — after releasing any SLOB inbound, every FCP player should immediately cut toward the basket if their defender sagged to help on the primary action. This is not a called play. It is a habit that turns every SLOB into a 5-on-4 after the catch. It takes one rep to install and defenders almost never guard it because the inbound stance freezes them.
- Install the Alabama Stack Backdoor first — one alignment, one DHO-fake trigger, one backdoor read. Most teams can execute it correctly within 15 minutes of practice time.
- Carry the Spurs EOG 3 as your designated "down 3, under 8 seconds" SLOB call — three screens, one 3-point catch, one inbound pass. Answer the "2 or 3?" question before calling it.
- Enforce the Jay Wright shoe-tie rule: the inbounder waits until all four players make eye contact and signal their spot before taking the ball from the referee. Non-negotiable SOP.
- Teach inbounder back-cut as a universal discipline, not a play call — any time the inbounder's defender sags to help after the ball is released, the inbounder cuts hard backdoor immediately.
- Against zone on SLOBs, flash a big to the mid-post or elbow first — the zone cannot cover the middle and the perimeter simultaneously, and this single action creates an open look in one pass.
- Cap the SLOB menu at three plays per team: one quick-hitter shooter set, one two-phase flow set, and one backdoor set. Automatic execution of three plays beats confused execution of six every time.
