The pack line defense, or packline defense, is a half-court defensive basketball strategy that aims to decrease dribble penetration into the key. A traditional [man-to-man defense](https://www.masterclass.com/articles/man-to-man-vs-zone-defense) relies on a singular on-ball defender putting pressure on the ball handler, while auxiliary defenders cover passing lanes to the wings. In a pack line defensive package, all the “help defenders” stay near an imaginary line, roughly sixteen feet from the hoop. This line mirrors the arc of the three-point line. In creating this perimeter that extends from the free-throw line to the baseline, this compact [defense](https://www.masterclass.com/articles/basketball-defense-guide) forces a point guard or other offensive player to settle for attempting jump shots instead of open layups.
In 2003, Washington State University Head Basketball Coach Dick Bennett developed the pack line defense to combat college basketball teams with a dominant post player and weak outside shooters. His son, Head Coach Tony Bennett, implemented the same defensive strategy to take the University of Virginia Men’s Basketball Team to the NCAA Final Four Tournament in 2014. After its 2014 showcase, the pack line became a popular defensive strategy for other winning programs, including Xavier University and the University of Wisconsin.
Consider these basic principles of the pack line defense to understand how this strategy can accomplish a basketball team’s objective: 

- __Front the post player__. Since offensive post players traditionally set up in the low post position at the bottom block of the key (the paint that extends forward from the basket), the post defender should deny any incoming pass from the wing. To front a player in post defense, you shift your position between the post player and the ball handler slightly. High hands and a sturdy base will prevent you from losing this positioning, but don’t overcommit. A well-placed lob pass can give the post player an open path to the hoop if you are unable to rotate back to your original position. If you find yourself in an unbalanced matchup, <a href='https://masterclass.com/articles/robin-robertss-tips-for-effective-communication' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/robin-robertss-tips-for-effective-communication","linkCopy":"communicate","category":"automated-link"}' automatic='true'>communicate</a> with high-side defensive players (the side the ball is on) or weak-side defensive players to double-team your assigned player if they receive the ball inside.
- __Provide on-ball and off-ball pressure__. The defender guarding the player with the ball must focus on tight and aggressive defense fundamentals. But it is important that this defender will not be overly aggressive and reach for steals. An unsuccessful steal attempt can result in reach-in fouls, or the dribbler could beat the defender. In team defense strategies, when a player is beat, it forces the rest of the defense to rotate assignments (the players they’re assigned to guard) until the on-ball defender can recover. Off-ball defenders should remain near the pack line until their assignment receives a pass. Once their assignment has possession of the ball, it is now the defender’s turn to leave the pack line and apply pressure defense with a swift and controlled closeout. 
- __Stop the transition__. The pack line can be a great defense against teams who prefer to control the tempo with methodical half-court plays. However, it can be inefficient in combating teams who run a fast-paced transition offense. It is, therefore, the job of the [point guard](https://www.masterclass.com/articles/key-basketball-positions) and at least one of the wing players to stay near the top of the key while two to three of their teammates crash the boards (reach for the backboard) to recover offensive rebounds. These two players quickly transition from attacking on offense to becoming <a href='https://masterclass.com/articles/how-to-write-a-great-first-line-for-your-novel' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/how-to-write-a-great-first-line-for-your-novel","linkCopy":"the first line","category":"automated-link"}' automatic='true'>the first line</a> of defense against the fast break. A pack line transition defense should appear like a strategic retreat. All defenders will sprint to get back to the pack line and regroup before addressing their respective assignments.
Consider the following strengths of this compact basketball defensive strategy:

1. __Advantageous defensive rebound positioning__: Since off-ball defenders are closer to the hoop than traditional man-to-man defenses, they are in a better position to claim the rebound off a missed shot. It is essential that each player boxes out their opponent to stop them from getting a second scoring opportunity. 
2. __Defense support for post players__: Dominant post players can wreak havoc on a defense, especially at the high school level. The compact format of the pack line defense provides outmatched post defenders with nearby support against taller and stronger offensive players. 
3. __Deterral of interior penetration__: Interior shots generally produce a higher field goal percentage, but the pack line crowds the interior and helps deter agile ball handlers from attempting to dribble into the key. The offense is then forced to settle for more difficult outside shots.
Every basketball defense strategy has a weakness, and the pack line set is no exception. 

1. __Dependency upon patience__: A head coach must instill his team with steadfast patience and discipline for the pack line defense to be successful. If players stray too far from the pack line and attempt to steal a pass, they can find themselves out of position or beaten by a backdoor cut. This patience is especially critical in leagues that do not use shot clocks because the offensive team can pass the ball around the perimeter until the defensive rotation breaks down.
2. __Ineffectiveness against strong outside shooters__: Sharp-shooting NBA scorers like Steph Curry forever changed the philosophy and utility of the three-point shot. In recent years, the emphasis of scoring evolved from an interior attack to a focus on ball rotation and perimeter shooting. Due to this offensive renaissance, many players adapted by improving their jump shot. This improvement in outside [shooting](https://www.masterclass.com/articles/how-to-shoot-a-basketball-with-steph-curry) has made the pack line defense obsolete in defending teams at many levels of play. 
3. __Vulnerability to the pick-and-roll offense__: The Achilles’ heel of the pack line defense is the [pick-and-roll](https://www.masterclass.com/articles/learn-the-pick-and-roll-from-basketball-pro-steph-curry) offense strategy. The pick comes from the offensive post player, who sets a ball screen on the on-ball defender, meaning the offensive player uses their body as a blocking screen. If the on-ball defender does not fight their way through the screen, the screener can seal off the smaller defender and then roll toward the hoop undeterred. Without communication and effective help defense, pick-and-roll maneuvers from the offense can be devastating to a team running a pack line defense.
