There are eight ways to guard a ball screen and every one of them gives something up. That is not a flaw in any of them; it is the whole nature of the action. Two offensive players occupy three defensive jobs — the ball, the roll, and the space between them — and somebody has to be late.
So the useful question is never “what is the best coverage”. It is “what is this team willing to give up tonight, and do we have the shot that punishes it”.
The eight coverages
Drop
The screener’s defender retreats toward the rim. The guard fights over the top and chases from behind. Nobody switches and nobody leaves their own man.
Why a team plays it. It asks the least of everybody else. No rotation to remember, no shooter left alone, and a rim protector stays at the rim, so one screen almost never produces a layup. It is also the honest answer for a big who cannot move his feet out on the floor.
What it concedes. The space between the screen and the big: a pull-up from twelve to eighteen feet (3.5 to 5.5 m), or a three if the drop is deep and the guard is a step slow.
How to attack it. Shoot the shot it gives you. Throw the pocket pass before the big commits. Re-screen so the chasing guard has to get through twice. Or pin the dropping big with a back screen so he is not at the rim at all.
Coaches do not agree on how deep “drop” is — some mean the big at the level of the screen, chest on the dribbler’s inside shoulder, and others mean the front of the rim. Say which one you want, because the shot you give up is not the same.
Under
The guard ducks underneath the screen and meets the dribbler on the far side. No switch, no help.
Why a team plays it. Because the handler will not shoot it. Going under takes the whole drive away and dares him to rise up.
What it concedes. The pull-up three, immediately and every time.
How to attack it. Shoot it if you can. If you cannot, re-screen — the second screen catches a defender who has just given up his position and has to fight through the right way this time.
Over
The guard fights over the top of the screen and stays attached to the dribbler’s hip.
Why a team plays it. To keep a shooter from shooting. Over is what you play against the handler you cannot leave.
What it concedes. The downhill drive. A guard going over is a step behind by definition, so the coverage only works if the screener’s defender is doing something useful behind it.
How to attack it. Reject the screen. If the guard is committed to going over, the space is on the other side. A slip or a ghost punishes the same commitment.
ICE
On a side screen the on-ball defender jumps to the high side and refuses the screen, pushing the ball down the sideline toward a waiting big. Other staffs call it blue, down or push; it is the same instruction.
Why a team plays it. It keeps the ball out of the middle, where the help is thinnest, and it turns a two-man game into a one-man game against the sideline and the baseline.
What it concedes. The baseline side of the floor, the short corner, and the ball handler’s strong hand if you ICE him toward it. It also leaves the screener free for a beat.
How to attack it. Reject it and drive middle at the defender who has just vacated. Re-screen from the other angle so the sideline is no longer a wall. Or keep the ball and let the screener slip into the space the coverage created.
A screen at the top cannot really be iced — there is no sideline close enough to push the ball toward — so most teams play the middle screen straight up.
Hedge
The screener’s defender steps out into the dribbler’s path for a beat to slow him down, then runs back to his own player.
Why a team plays it. It buys the chasing guard the time to catch up without giving up the rim or a switch.
What it concedes. The roll, for exactly as long as the hedger is out there. Everything depends on the recovery.
How to attack it. Ram the hedger. A screen on the screener’s defender before the ball screen means he arrives late and cannot get out in time.
Some staffs reserve “show” for a softer version that never leaves the level of the screen and “hedge” for the committed one. Plenty use the two words for the same thing. Ask before you argue.
Hard hedge
The same idea, further out. The big jumps above the screen and pushes the dribbler backward toward midcourt before recovering.
Why a team plays it. To kill the rhythm of a ball handler who is beating everything else, and to make the offense use up clock getting back into the action.
What it concedes. More than a hedge does: the roller gets a real head start, and the two defenders behind the ball have to cover the short roll.
How to attack it. Short roll into the middle of the floor and play four-on-three from there. Slip the screen before the hedger has committed. Or ram the hedger.
Switch
The two defenders trade players.
Why a team plays it. It is the cleanest answer to a screen — nobody is ever late — and against a team with five similar bodies it costs almost nothing.
What it concedes. A mismatch, and the offense gets to choose which one. Either a guard is now on a big, or the big is chasing a shooter.
How to attack it. Attack the switch immediately, before help arrives. Screen for the smaller defender’s man and seal. Or use a ghost, which punishes a switching team by trading a dangerous guard for a worse defender and never making contact at all.
Blitz
Both defenders trap the ball handler. Three defenders cover four.
Why a team plays it. To get the ball out of one player’s hands, full stop. It is a scout coverage and a late-game coverage.
What it concedes. A four-on-three every time the ball escapes. That is a shot somewhere if the offense is ready.
How to attack it. Get off it early — the pass out of a trap has to leave before the second defender arrives. Then play the short roll: the roller catches in the middle of the floor and reads the low man. A team that practices the short roll beats a blitz; a team that does not, turns it over.
Off the ball
The same logic applies to pin-downs, flares and staggers, with four choices instead of eight:
- Chase (lock and trail). Get on the cutter’s hip and trail him over the screen. Takes away the catch-and-shoot, concedes the curl.
- Top-lock. Stand between the cutter and the screen so he cannot use it. Concedes the back cut and the flare — which is exactly why a good staff pairs a stagger with a flare as its counter.
- Under. Take the short way and meet him on the other side. For a cutter who will not shoot.
- Switch. Simple, and the same mismatch problem as on the ball.
Handoffs get three: over, under, or switch. A dribble handoff is a moving screen you cannot switch cleanly, which is why so many offenses live on them.
Picking one
Work backward from your personnel, not from a book.
- A big who cannot move his feet out on the floor. Drop. Live with the pull-up.
- A big who can. Hedge, and let the guard chase over.
- Five similar bodies. Switch, and take the simplicity.
- One handler doing all the damage. Blitz him in the fourth quarter and make somebody else beat you.
- A young team. Drop, and nothing else, until the footwork is there.
Then check the other half of the question: when a team plays that coverage against you, do your players know what to do about it? That is the part most staffs skip, and it is the cheaper half to fix.
One practical way to work on it: draw the possession once, set the on-ball screen coverage, and replay the same action against a different one. SlongeHoops does this with a simulated defense that is still in Beta — it shows you where five defenders end up, and it does not pretend to decide whether the shot goes in. Seeing a roll get tagged is enough to change what you tell your 5 to do.
The counter that matters most is the one you have already practiced. Two per coverage is plenty.
Questions
What are the main pick-and-roll coverages?
Drop, going under, going over, ICE, hedge, hard hedge, switch and blitz. They differ in what the screener's defender does and in whether the two defenders trade players.
What is the difference between a hedge and a show?
Many staffs use the words interchangeably. Where they are distinguished, a show is the softer version — the big steps into the dribbler's path for a beat without leaving the level of the screen — and a hedge commits further out before recovering.
How do you beat drop coverage?
Take the pull-up the coverage gives you, throw the pocket pass into the gap before the big commits, or re-screen so the chasing guard has to fight through twice. A back screen on the dropping big, as in Spain pick-and-roll, removes the rim protection entirely.
Can you ICE a screen at the top of the key?
Not in the usual sense. ICE works by pushing the ball toward a sideline, and a screen in the middle of the floor has a sideline on both sides. Most teams play a middle screen straight up and save ICE for the wings.
Which coverage should a youth team play?
Drop, and only drop, until the bigs can move. It asks nothing of the other three defenders, needs no rotation, and never gives up a layup off one screen. Everything else can wait.
