学点篮球端正 之 篮下防卫时怎样“碰”不犯规
湖人与凯尔特人的比赛，詹姆斯在比赛常规时间最初时候被犯规惨遭漏判。依据NBA官方公布的《Official Playing Rules 2022-23 NBA Season》端正，实用于此中以下条款：
B. Personal Foul
Section I—Types
b. Contact initiated by the defensive player guarding a player with the ball is not legal.
This contact includes, but is not limited to, forearm, hands, or body check.
即 由防卫球员倡导的对持球球员的交往是犯规。（这种交往包含但不限于对前臂、手大概贴身）
那篮下防卫怎样“碰”才干不犯规呢，依据此NBA划定，防卫队员交往持球对手而不犯规的情况有以下几种：
(1) A defender may apply contact with a forearm to an offensive player with the ball who has his back to the basket below the free throw line extended outside the Lower Defensive Box.
即 当持球打击队员身处分球线到低位防卫区外（如下图黑框所示地区）时且背向篮筐，防卫队员可以用前臂交往持球的打击队员。（前臂只是用来坚持防卫地点）
可用前臂地区
(2) A defender may apply contact with a forearm and/or one hand with a bent elbow to an offensive player in a post-up position with the ball in the Lower Defensive Box.
即 当持球打击球员在低位防卫地区内（如下图紫色框所示地区）背筐打击地点时，防卫球员可以用前臂和/或弯曲的手肘举行交往。（前臂只是用来坚持防卫地点）（比拟前一种情况可用肘部）
可用前臂+肘部地区
(3) A defender may apply contact with a forearm to an offensive player with the ball at any time in the Lower Defensive Box.
即 当持球打击队员在低位防卫区中时，防卫队员可以用前臂交往此打击队员。（前臂只是用来坚持防卫地点）
(4) A defender may position his leg between the legs of an offensive player in a post-up position in the Lower Defensive Box for the purpose of maintaining defensive position. If his foot leaves the floor in an attempt to dislodge his opponent, it is a foul immediately.
即当打击球员在低位打击地区背框打击时，防卫球员为了坚持防卫地点可以把腿放在打击队员两腿之间；但假如防卫报答了将对手赶走而脚分开地板则是犯规。
(5)Incidental contact with the hand against an offensive player shall be ignored if it does not affect the player’s speed, quickness, balance and/or rhythm.
即 在不影响球员的速率、敏捷、均衡和/或节奏的情况下，偶尔交往打击球员的手的情况应被忽略。
小编以为第5种情况给了裁判一定的机动度，有一定的支配空间。
一切的端正都是为了更好的促进活动，保护运倡导，学习端正使用端正也是对一切到场者的保护。篮球喜好者平常组局时本着友好协商的准则，公平对待球友，保护本人。
