Defence
Defending on-ball screens


sketch
1
Pushing out

The on-ball defender (xdribbler) tries to force the dribbler out and away from the screen, with no defensive rotation. If the dribbler makes a dribble back and tries to use the screen again, the screen defender (xscreener) can jump out to help then quickly recover.

Alvin Gentry - hold your ground when guarding the ballhandler, don't allow him to locate the ball below the hashmark. Be physical guarding the screener, hold him up, don't let him run in a straight line to set a ballscreen. This combination moves the ballscreen further away from the basket.

Scott Clark - black - force the ball away from the screen, xscreener helps.

Ken Shields - fan - xscreener drops off the screener into the driving lane to the basket, xdribbler forces the dribbler away from the screen toward xscreener. It takes five players to defend ballscreens, the other players take two steps off their men and are ready to rotate to open men. Pick and roll is now very important because of the 3-point shot, have at least 2-3 ways to defend and know how you will start the game.

Weak

The on-ball defender forces the ballhandler to use the weak hand, but cannot allow a straight-line drive. The screen defender sags off his man to help protect against a drive, then recovers. X2 "stunts" (fakes) towards screener 4 to help buy time for X4 to recover.

Option - X4 traps with X1.

Jeff Van Gundy - against a straight-on ballscreen, always play weak with no confusion, xscreener plays soft between the ball and the basket, drops to the dots, or can show.
 
Jamie Dixon - go weak on a head-on ballscreen, X1 forces 1 to his weak hand, X4 hedges, X1 goes through (over the screen, under X4).

Show (hard hedge) and recover

The ballhandler is a dangerous outside shooter, in scoring range, and the screener is not a threat. The on-ball defender gets "thinner" or "skinny" and goes over both the screener and xscreener.

Here attacker 4 sets a screen for ballhandler 1. The defender of the screener, X4, calls "left" and steps out on the screener's top hip to fake a switch or trap, forcing 1 to pick up the dribble or change direction away from the basket, and giving on-ball defender X1 room to go over the screen. X4 then drops back quickly to stop a pass to the screener. X4 stays attached, keeping one hand on 4 as a "feeler". The hedger doesn't jump out too early or will get split by the dribbler.

Mike MacKay - by sliding over the screen, xdribbler is vulnerable to the dribbler faking to use the screen and then driving baseline, so xdribbler "muscles" the pick, turning sideways, forcing the dribbler to use the screen, and using his forearms to bulldoze through the screen, with one forearm on the hip of the dribbler and the other on the hip of the screener. By showing his chest, xscreener takes away the passer's vision, making it difficult to pass to the screener.

Morgan Wootten - xscreener steps out into the path of the dribbler and hedges to delay and contain the ball, allowing xdribbler time to fight over the screen and get back in front of the dribbler.

Mike Fratello - show and over - as soon as he hears "left", xdribbler jumps on the bottom side to take the ball to the screen, and gets up into the ball, closing down the space.

Roy Williams - they defend ballscreens three ways, in each case xscreener shows high. Show high and go over is the regular way, X4 shows with his right hand touching 4 (in case the screener slips to the basket), then gets back. They will also trap, or show and go under (see below).

Ken Shields - xscreener must show on a ballscreen inside 3-point range, a weakside big covers the screener if he slips to the basket.

Larry Brown - defending an elbow (Horns) ballscreen, no hedge is needed, xdribbler goes over the screen.

Show high-low

coachesclipboard.ca - over-under - the xdribbler goes over the screen but under xscreener, effective where the ballhandler is a good penetrator and shooter but the screener is not a perimeter shooter. X4 calls out the screen, stays with an arm bar on the top hip of the screener, then steps out high with a hard hedge ("show your numbers to the ball"). X1 stays on the ballhandler's inside hip, forcing 1 to use the screen, then goes over the screen and under X4 to get into position between 1 and the basket. X4 recovers to 4 as soon as X1 goes under (not earlier or X4 will usually run into X1). Help rotation may be necessary if 4 is temporarily open rolling to the basket.

Mike Fratello - early hard show, over and under - X4 has his inside hand down to prevent a split on the dribble.

Jeff Van Gundy - show high-low - X1 can go over the screen or under it (the higher the screen, the worse the shooter), see show and under.

Kevin O'Neill - show high-low - X4 shows high, X1 goes over the screen but under X4. If you show high, stay high. X5 takes roll guy 4, meeting him high and standing him up.

Tom Izzo - up and over - X4 steps straight up then back, X1 goes under him but over the screen.

Alvin Gentry - if not executed properly, xdribbler and xscreener will run into each other.

Larry Brown - this is his primary way to defend ballscreens. A baseline drive, ballscreen, and low-post trap all have the same rotation concept - two interceptors and a goaltender, players are interchangeable.

Scott Clark - hedge over/under - make the early slip beat you.

Bob Hurley - xscreener shows on middle ballscreens, stepping out just beyond the screen with his feet parallel to the screener's, reaching out with his top hand and halting the dribbler while he pulls his teammate through the screen with his other hand.

Show and under

Mike Fratello - show and under - the xscreener shows in the dribbler's path, xdribbler goes under the xscreener and the screener.

Tom Izzo - up and under - xscreener steps straight up but maintains contact, xdribbler goes under the screen (the dribbler is a good shooter but not a handler, he won't turn the corner).

Mike Mackay - under/hedge - some teams are starting to use this, xdribbler goes under the screen while xscreener shows a high hedge, forcing the dribbler high and giving xdribbler time to recover. The best counter is a re-screen, catching both defenders on the other side, or the screener sprints to space.

Alvin Gentry - anytime a ballscreen is set clearly above the NBA 3-point line, xdribbler goes under the screen. When defending ballscreens against great players, choose what to give up, e.g., when defending John Stockton go under a ballscreen, give up a jump shot rather than deal with Stockton's penetration.

Roy Williams - if the dribbler is not very good at pulling up and shooting, they allow X1 to go behind but X4 still shows high.

Scott Clark - 12 - is very good vs. pick and pop, the show man should recover to the passing lane.

Bob Hurley - we don't go under ballscreens, screw the scouting report that says he's a non-shooter, we're St. Anthony, we don't go under ballscreens here.

Soft hedge and through

The ballhandler has limited shooting range and/or is a great dribble penetrator. The xdribbler calls "gap" and goes through the screen, i.e., between the screener and xscreener. X4 forces ballhandler 1 laterally across the court, leaves room for X1 to go through the screen, pushes X1 through on the hip, then recovers to the screener.

Mike Fratello - open and through - X4 has at least one-dribble responsibility for the dribbler, and stays between the ball and the basket until X1 is through.

coachesclipboard.ca - 1 under - the dribbler is not a good shooter, the screener is a perimeter threat.
 
Marc Iavaroni - a smart team will not attack the ball (show or blitz) when the pick and roll is outside the scoring area, they will just corral the ball. As a counter, the screener gets below the ball then below the on-ball defender (a fish-hook screen), where going under the screen makes no sense. Also set a fish-hook screen against attacking or switching ballscreen defence.

See sag.

Soft hedge and over

Mike MacKay - over/hedge - the xdribbler goes over the screen while xscreener stays in the small of the screener's back and shows laterally, not allowing the dribbler to turn the corner. Again, this is vulnerable to X1 faking to use the screen and driving baseline.

Tom Izzo - feather - xscreener soft hedges sideways, xdribbler goes over the screen, xscreener pulls him through then gets back to the screener (worried about the dribbler turning the corner, also about pick and pop).

Xavi Pascual (FIBA Assist 37) - xdribbler aggressively goes above the screen, xscreener goes out in line with the screen, preventing the dribbler from splitting the screen, then recovers when xdribbler is ready to recover on his man.

sketch

Squeeze and under

The ballhandler is not an outside threat. The xscreener plays tight (jam or hug the screener), forcing the screener out into the ballhandler's path, and xdribbler goes under both players, protecting against a drive.

Used to defend the pick and pop when the screener is a dangerous outside shooter; also defends the roll by being between the screener and the basket. Often used when the ballhandler is outside shooting range. The xscreener puts up his hand to disrupt any shot.

Bob Huggins - if xscreener can re-route the screen above the arc, then squeeze or gap; if the screen is inside the arc, trap or show and go over. X5 absorbs the roll on a trap.

Mike MacKay - the dribbler is not a shooter but the screener is, xscreener pushes up tight to the screen with a hand up, giving xdribbler lots of room, and making it difficult for the screener to roll or sprint to space.

Tom Izzo - jam - 1 is not a good shooter, 4 is a great player.

Alvin Gentry - squeeze and under is a great way to defend a middle ballscreen. You have to squeeze anytime xdribbler goes under, otherwise the screener can move down closer to the basket.

Ken Shields - squeeze and go under a high ballscreen outside 3-point range, xscreener bodies his man up and out to extend the screen, xdribbler goes under to cut off dribble penetration. Good against a pick and pop shooter.

coachesclipboard.ca - 2 under - the screener is an excellent shooter (pick and pop), the dribbler is not a deep-range shooter or great penetrator. The xcutter must be quick to get under, and xscreener must be tight to the screen, not in xdribbler's path.

Larry Brown - when xdribbler goes under the ballscreen, the screener automatically turns for a re-screen, automatically trap the re-screen.

goxavier.com - switch on any re-ballscreen, xscreener does not have a good angle to hard hedge (xdribbler goes under the screen to switch).

Trap (blitz)

The dribbler is a major threat. The xscreener steps out to trap as the ballhandler draws even with the screen. The xdribbler forces the dribbler to use the screen then fights over it. The screener is picked up by the nearest defender and the defence rotates to leave the least dangerous player open. If the dribbler stretches the trap by dribbling back towards mid-court, defenders recover to their checks. Rotate early if the screener is a shooter.

If the ballhandler completes a pass to the screener on the roll, a coaching option is another trap on the ball by xscreener and the help defender (here X4 and X5).

coachesclipboard.ca - trapping may fit into an overall strategy of being very aggressive, the danger is the screener slipping the screen or picking and popping to the perimeter.

Tom Izzo - they want to get the ball out of the dribbler's hands, stay with him, work to get back (recover) on a pass out.

Kevin O'Neill - stay with the trap until 2 passes or takes two hard dribbles towards midcourt.

Mike MacKay - trap the ballhandler as soon as he dribbles, other players rotate to cover the next logical passes. To counter, drag the trap as far back as possible, creating gaps that can be split and making recovery more difficult on a pass out of the trap.

Alvin Gentry - guards in the NBA are too good to trap on ballscreens, and the opposite low-post attacker punches into the middle of the lane, making the rotation very difficult to get in front of.

goxavier.com - the closest defender rotates to the screener when a trap happens.

Bob Hurley - trap all side pick and rolls because at the high school (and even college) level, teams don't move their weakside attackers enough to hurt you when you bring your helpside defenders over to cover the roll guy.

sketch
10
Here a midscreen trap is shown. X3 and X5 rotate to help on the roll to the basket, preventing a catch on the roll, or at least a deep catch. Defenders use closest-man rotation on a pass out of the trap.

Some coaches will automatically trap a re-screen, especially after squeezing the first screen.

Mike Fratello - X4 will recover to the roller if 4 is not a shooter. Recover with both arms up even though you can't see the ball.

Jeff Van Gundy - as the screener rolls to the basket, X5 steps up to meet him hard as early as possible, X4 stays high to take 5 who comes up to replace 4.

Roy Williams - on a double team, somebody comes up on the screener, everybody gets involved.

Ken Shields - trap early or late, the three other defenders must get in spots to help and may have to rotate to an open player on a pass out of the trap.

Xavi Pascual - maintain the two-on-one until 1 makes a pass, X4 quickly recovers to his man except if 1 goes very far from the basket and X4 needs to make a long recovery, then the big men switch. If 1 penetrates there is no help from strongside X2, at most they will let him fake and recover on the passing line, with his body perpendicular to the passing line. Weakside X3 leaves his man to attack the roll to the basket.

Trap early

To get the ball out of the hands of a good player when the screener is also a threat, the ballhandler is trapped before the screen is set (and even if it is not set). Other defenders rotate to cover, e.g., if the screener slips the screen.

goxavier.com - against a great player, blitz him before a sidescreen is set.

sketch
12
Switch

The ballhandler is shaky or the screener is a threat. The xscreener jumps into the ballhandler's path (or at least moves up beside the screener) and switches as the ballhandler passes the screen. The xdribbler immediately picks up the screener, going behind the screener to jam and deny the roll (switch under), or he fights over or partway over the screen to defend the roll (switch over). Either defender can call "switch". Switching is riskier on big-to-small or small-to-big screens unless the two defenders are the same defensively.

Hoop Tactics - switch on ballscreens above the foul line extended, trap (or trap early) below it.

Mike Fratello - xdribbler has to get under the screen, the switch can be parallel or xscreener can jump out to send the ball back where it came from, which is a little harder.

Mike MacKay - going under prevents the screener from rolling to the basket and running to space, but you get caught behind him and are easily posted; going over gets a front position and can force a more difficult pass, but you can get sealed on the roll.

Kevin O'Neill - switch on a small-small or big-big ballscreen, or the last 8 seconds regardless of size. X4 is at the level of the screen, hand on, jumps the dribbler hard, X1 goes behind the screener to pick him up (i.e., show and switch under).

coachesclipboard.net - they jump-switch ballscreens, xscreener jumps out on the ball, switches and stops dribble penetration, xdribbler aggressively steps around the screener (switch over) to prevent a bounce pass, low help players defend a lob pass (going under the screener may be easier but is more vulnerable to a bounce pass). Don't switch if the dribbler goes the opposite direction, xscreener steps around the screener to deny a bounce pass.

Scott Clark - always switch with under 7 seconds on the shot clock.

Ken Shields - equal-size defenders may switch, and switch ballscreens 15 feet and in (trap a mismatch).

coachesclipboard.ca - switch if defenders are of similar size.
 
Eddie Fogler - when in doubt, switch on a ballscreen. If their best player is coming off a ballscreen, trap and force someone else to beat you.
 
See show and under.

Sag (shadow, soft)

The ballhandler is a penetrator and the screener is not a threat. The xdribbler fights over the screen while xscreener sags to defend dribble penetration.

Also used to defend random or transition ballscreens (along with squeezing). The xscreener drops off and zones up, xdribbler goes over or under the screen (drop and plug).

Alvin Gentry - drop and plug against random ballscreens on the break, there is no hedge, xdribbler can go over or under the screen.

Jeff Van Gundy "soft" - the xdribbler forces the dribbler to use the screen, xdribbler goes over or under it, xscreener stays between the ball and the basket, retreating (like a soft trap), or drops to the dots in the paint.

Mike MacKay - under/sag - the dribbler and screener are not shooters, or the screen is set outside the scoring area, the xscreener must communicate the screen early and often to avoid an open-court screen that frees a penetrator, xdribbler goes under the screen. Over/sag (xdribbler goes over) is not a promoted way of defending but is often used because xscreener is late. To counter, have the screener sprint to space.

Force outside

coachesclipboard.ca - the screener is not a perimeter threat and the defence wants to keep the ballhandler out of the middle. The xdribbler quickly gets above the screen so the dribbler can't use the screen to drive middle, xscreener drops off the screener towards the baseline to help prevent penetration. If the screener rolls to the basket, xscreener will get help from weakside defenders. Teams may also choose to trap the dribbler with xdribbler and xscreener.

Also known as "ice", pushing the sidescreen down, forcing it baseline, or fanning, forcing outside is especially effective with an attacker (and therefore help) in the ballside corner.

Avery Johnson - sidescreen and close-out defence should be consistent. If the close-out is high-side, forcing baseline, then force the pick and roll baseline, trap, and rotate to leave the furthest attacker open (X1 takes 4). If the close-out is low, forcing middle, send the dribbler towards the screener but trap early before the screen is set.

Jansen (coaching.fibaeurope.com) - use fanning when the screener can't shoot or with a great shot blocker. Switch or trap, the closest high perimeter defender (here X1) rotates to cover the escape pass to the screener at the high post. The offensive counter to fanning is a step-up ballscreen on the baseline side.

Jeff Van Gundy - "down" the ballscreen when there is an attacker in the ballside corner. A good attacking team will counter by using a step-up screen, so the dribbler can use it and go baseline.

Mike Fratello - ice - the screener will dive or step back for a jump shot.

Tom Izzo - turn down (black) - 4 can't shoot, X2 doesn't let 2 get to the screen, X4 (a shot-blocker) drops down.

Kevin O'Neill - blitz a step-up ballscreen until a pass, use the sideline and baseline to trap.

Mike MacKay - teams that use a sidescreen run a shooter to the corner, making it difficult to defend with rotating help defence, so don't allow the offence to use the screen. X2 gets into an extreme force position not allowing 2 to dribble to the middle, X4 sags to help on the baseline drive. A common counter is to re-screen, and step the screener out for a pass. The screener then passes and follows to ballscreen, xscreener must recover quickly to help.

Alvin Gentry - guarding the ballhandler on a sidescreen, force him to use the screen, a baseline drive creates problems for the defence.
