THE SHORT VERSION
- The NBA’s two videos cover off-arm push-offs, screens, perimeter and post movement, and straight-line drives.NBA两段视频涉及不持球手臂推人、掩护、外线与低位移动，以及直线突破路线。
- Officials are asked to distinguish feeling or firming with an arm from forceful pushing and full extension.裁判需要区分用手臂感知防守人与强力推开、完全伸臂的动作。
- Viewers can track whether contact holds, pushes, grabs or redirects another player instead of treating every touch as a foul.回放时可观察接触是否拉住、推开、抓住或改变其他球员路线，而非把每次碰撞都当犯规。
Two videos organize four kinds of contact两段视频围绕四类身体接触
For 2026-27, the NBA published two points-of-emphasis videos on September 29. Part 1 covers off-arm push-offs by offensive players and freedom of movement on screens. Part 2 covers freedom of movement on the perimeter and in the post, plus straight-line pathway plays. The subjects overlap because each asks whether contact is part of a basketball action or changes another player’s movement.NBA于9月29日发布了2026-27赛季的两段执法重点视频。第一部分讲进攻球员用不持球手臂推开防守人，以及掩护中的移动自由。第二部分讲外线与低位移动中的移动自由，以及直线突破路线。主题有所重叠，因为每个例子都在区分篮球动作中的接触与改变其他球员行动的接触。
The league also explained the examples in an NBA.com feature. It described the annual emphasis as guidance for players, coaches and referees, with the league planning to visit each team and show the videos. That makes the clips a viewing guide for particular contact patterns, not a promise that every similar play will draw the same call. The official NBA page names the four video topics.联盟也在一篇NBA.com说明文章中解释了这些例子。文章称，联盟每年都会为球员、教练和裁判提供此类指导，并计划走访各队播放视频。视频可以帮助观众识别特定身体接触模式，却不保证每一次相似动作都会得到完全相同的判罚。NBA官方页面列出了四个视频主题。
Watch what the ball handler does with the free arm观察持球人如何使用不持球的手臂
On a drive, the arm away from the ball can help a player feel where a defender is. The NBA’s training explanation draws a line between that legal use and a forceful push. Referee-development chief Monty McCutchen said a player may firm up or feel for a defender, while forcefully pushing off or fully extending the off arm is illegal. The distinction is the action and force, not merely whether the arm touches an opponent.突破时，球员不持球的手臂可以帮助他感知防守人所在位置。NBA的执法说明区分了这种合法动作与强力推开。负责裁判发展工作的蒙蒂·麦卡琴称，球员可以用手臂顶住或感知防守人，但强力推开或把另一只手臂完全伸直属于犯规。关键在于动作和力量，而不只是手臂是否碰到对手。
The NBA said it saw an increase in off-arm pushes used to create separation. In the examples, viewers should look at whether the player’s hand or forearm displaces the defender to open a driving lane or space for a shot. The league said it still wants skilled players to create separation to some degree. That means the instruction does not ban all contact with the off arm; it targets the extension used to move the defender.NBA表示，联盟看到球员用不持球手臂推开防守人、创造空间的情况增加。在视频例子中，观众应看球员的手或前臂是否把防守人推离位置，为突破或投篮拉开空间。联盟仍希望有技巧的球员可以在一定程度上创造空间。这意味着指导不是禁止所有非持球手臂接触，而是针对用伸臂动作移动防守人的情况。
Screen setters cannot create an advantage by holding or pushing掩护者不能靠拉扯或推动创造优势
The screen example shifts attention from a dribbler’s arm to the player setting the pick. The NBA says there are more than 200 screens in a game and is emphasizing two-handed screens that push or hold defenders. A screener can create an advantage for the ball handler without using both arms to move the defender toward midcourt or the sideline. The league says that contact can open a driving lane or make a pocket pass easier.掩护例子把注意力从持球人的手臂转移到设置掩护的球员。NBA称，一场比赛会出现200多次掩护，联盟正在重点关注用双手推动或拉住防守人的掩护。掩护者可以通过正常掩护帮助持球人创造机会，但不能用双臂把防守人推向中场或边线。联盟称，这类接触可能为持球人打开突破路线，也可能让口袋传球更容易。
A viewer can follow the defender’s path through the screen. If the screener’s arms hold the defender in place or push that player off course, the contact interferes with freedom of movement. The NBA.com article reports that the league wants greater consistency on these plays, which often happen away from the ball and before the pass reaches the scorer. That places responsibility on the screen setter’s action, not only the eventual shot or pass.观众可以观察防守人穿过掩护时的路线。如果掩护者用手臂拉住防守人，或把对方推离原路线，就干扰了对方的移动空间。NBA.com文章称，联盟希望更一致地处理这类动作，它们通常发生在球还没有传到得分手之前的无球区域。因此，裁判要观察设置掩护者的动作，而不只看最终投篮或传球。
Freedom of movement applies away from the ball too无球球员也享有移动空间
The second video extends the same principle to perimeter and post movement. The NBA’s example includes contact that prevents a player from moving freely without the ball. Blazer’s Edge describes a weak-side defender grabbing an offensive player as that player cuts toward the rim. The ball may be on the other side of the court, but the contact can still disrupt a route and keep a teammate from reaching an open area.第二段视频把同一原则延伸到外线和低位无球移动。NBA的示例包括妨碍无球球员自由移动的接触。《开拓者之锋》举例，一名弱侧防守人拉住正朝篮下空切的进攻球员。即使球在球场另一侧，拉扯仍会打断跑动路线，使队友无法到达空位。
The post example concerns position before the entry pass. A defender may use legal positioning, but holding or impeding a post player before that player establishes position limits the route into the lane. These examples broaden what viewers should watch: not only a hand check against the dribbler, but also a grip on a cutter or contact that blocks a post player from getting to a spot.低位的例子关注球传入之前的位置。防守人可以采用合法站位，但如果在进攻球员获得位置之前拉住或阻拦对方，就会限制其进入禁区。这些例子扩大了观众需要观察的范围：不只是对持球人的手部防守，也包括拉住空切者，或阻止低位球员到达预定位置。
The defender can contest the line without knocking the driver off it防守人可以沿直线防守，但不能把突破者撞离路线
On a straight-line drive, the NBA says the defender is entitled to defend along the path and has freedom of movement. The emphasis is not that the dribbler owns the lane without resistance. The difference is between occupying or guarding the line and using a bump to displace the dribbler from that route. The official video pairs the pathway language with the broader freedom-of-movement guidance.在直线突破中，NBA称防守人有权沿着突破路线防守，也享有正常移动空间。重点不是说突破者可以毫无阻碍地进入禁区。关键在于防守人占据或防守这条路线，与通过身体撞击把突破者挤离路线之间的区别。官方视频把路线原则与更广泛的移动空间指导放在一起。
This matters because a side collision can obscure who changed direction. The NBA.com explanation says a defender may defend along the straight line but cannot knock the dribbler off it. Blazer’s Edge likewise points to a body bump that redirects a player on a direct drive. When reviewing the play, the useful frame is the moment before contact: did the defender maintain a legal position, or did the contact alter the driver’s path?这一区别很重要，因为侧向碰撞可能让人看不清是谁先改变路线。NBA.com解释称，防守人可以沿着直线防守，但不能把突破者撞离路线。《开拓者之锋》也提到用身体撞击偏转直线突破球员的例子。回放时可看身体接触前的瞬间：防守人是保持合法防守位置，还是用接触改变了突破路线？
The emphasis still leaves room for legal defense重点仍为合法防守留有空间
The NBA describes the goal as allowing good defense and good offense to compete, while holding firm when players use the edges of the rules to gain an advantage. For off-arm contact, the league permits firming and feeling but rejects a forceful push or full extension. For a screen, the body can set a pick, but the arms cannot hold or shove the defender out of the way. The same standard asks what the contact does.NBA称，执法目标是让进攻与防守公平竞争，并在球员利用规则边缘获利时作出处理。对不持球手臂，联盟允许球员顶住或感知防守人，但不允许强力推开或完全伸臂。对掩护，身体可以建立掩护位置，手臂不能拉住或把防守人推开。同一原则关注接触造成了什么结果。
That distinction is important for spectators because video often freezes a point where two players touch. The instruction is not simply “contact equals foul.” It asks whether a player held, pushed, bumped or displaced someone in a way the rules prohibit. The league’s own explanation acknowledges that some plays fall near a judgment boundary. The new videos are intended to make officials and teams attend to the same concrete actions.这一点对观众很重要，因为视频经常会停留在两名球员刚好碰到的画面。联盟指导并不是“发生接触就吹犯规”，而是要求判断球员是否以规则不允许的方式拉住、推搡、撞开或挤偏对手。联盟自己的说明也承认，部分动作处于需要判断的边界。新视频的目标是让裁判和球队关注同样具体的动作。
A useful replay starts before the whistle回放时从哨声之前开始看
The best way to read these examples is to watch the full movement into the contact. On a drive, follow the off arm and the defender’s balance. On a screen, track whether the screener’s hands extend to hold or push. On a cut, look for a grab before the pass. In the post, notice whether the defender’s contact prevents the offensive player from reaching the spot. These are the actions named across the league’s videos and explanations.阅读这些例子的最好方式，是观察接触发生前后的完整动作。突破时，跟着不持球手臂和防守人的平衡看；掩护时，留意掩护者是否伸手拉住或推开防守人；空切时，找传球前有没有拉扯；低位进攻时，注意防守接触是否阻止进攻球员到位。这些动作都出现在联盟视频和说明中。
The NBA said its staff would visit each team so players and coaches could ask questions about the clips. The point is shared instruction, not a statistical prediction about how many extra fouls a season will produce. The feature offers examples and the league’s own distinction between legal contact and forceful displacement. Fans can use those same details when an official pauses play or lets physical contact continue.NBA称，联盟工作人员会走访各队，让球员和教练观看视频并提问。重点是统一指导，而非预测赛季会多吹多少次犯规。说明文章列出视频例子，并区分合法接触与强力推搡。观众可以使用同样的细节来理解裁判何时暂停比赛，或允许身体接触继续发生。
The videos define focus areas, not a new list of outcomes视频列出重点，并非宣布新的比赛结果
The NBA’s materials call these points of emphasis and areas of focus for 2026-27. Blazer’s Edge notes that leagues revisit officiating priorities each season, sometimes reinforcing rules already in place as game techniques change. The announcement and examples focus on specific motions: extending the off arm, using arms on a screen, impeding a cutter or post player, and moving a driver off a straight path.NBA把这些资料称为2026-27赛季的执法重点和关注领域。《开拓者之锋》指出，联盟每年会重新强调一些执法优先事项；随着球员技巧变化，有些规则会得到再次提醒。公告和视频聚焦明确动作：伸出不持球手臂、用手臂控制掩护、阻碍空切或低位球员移动，以及把突破者撞离直线路线。
For viewers, that specificity is more useful than expecting a sudden change in every call. A player can still use an arm to feel a defender, a defender can still guard a direct drive, and a screener can still make legal contact. The NBA is drawing attention to force that changes another player’s space or movement. A replay becomes easier to evaluate when it is tied to that exact action rather than to the player’s name or the shot’s result.对观众来说，这种具体表述比期待所有判罚突然改变更有用。球员仍可以用手臂感知防守人，防守人仍可沿直线突破路线进行防守，掩护者也仍可进行合法身体接触。NBA强调的是会改变他人空间或移动路线的力量。分析回放时，把注意力放在具体动作上，比根据球员名字或投篮结果下结论更可靠。
