先看反跑如何完整运转 · See how the Backdoor Cut flows end to end
当防守者上抢封锁传球线时，接球人先向外伸手要球把防守带高，随后外侧脚蹬地，突然从防守身后直线切向篮筐；传球必须提前送到切入者身前，让其不减速完成终结。 · When the defender overplays the passing lane, the receiver steps out and shows for the ball to draw the defense high, then plants and cuts hard behind the defender straight to the rim. The pass leads the cutter so they never have to slow down.

防守怎么守 · How it is guarded
怎么防守反跑？ · How do you defend the Backdoor Cut?
每一种守法都要放弃一点东西，问题只是放弃哪一点。下面是常见的几种，以及它们各自留下的口子。 · Every coverage gives something up; the only question is what. These are the common ones and the opening each of them leaves.
沉退拉开 · Play off the catch
防守者退开一步，不再抢传球路线，把接球让出来但守住往篮下走的那条路。 · The defender backs off, stops fighting for the passing lane, and concedes the catch to protect the drive.
进攻怎么打： · What beats it: 这是唯一真正克制反跑的守法，因为反跑需要防守先犯错。退开一步就意味着让出接球和投篮——接住直接投是应有的回答。 · This is the only coverage that genuinely takes the backdoor away, because a backdoor needs the defence to make a mistake first. Backing off concedes the catch and the shot, and taking that shot is the correct answer.
弱侧封篮 · Low man rotates
反跑一启动，弱侧最低的那名防守者就转过来封篮筐。 · As the cut starts, the lowest weak-side defender rotates across to meet it at the rim.
进攻怎么打： · What beats it: 他一转身，他守的那个人就空了。反跑者不一定要接球——把防守拉过来之后，球直接甩到他刚离开的那个底角同样成立。 · The moment he rotates, the man he left is open. The cutter does not have to receive the ball: dragging that defender across and then skipping it to the corner he vacated is the same possession.
换防 · SwitchSWITCH
反跑往往发生在无球掩护之后，防守用换防让掩护失效，也就没有可以钻的空当。 · Backdoors often come off an off-ball screen, and switching it removes the gap the cut was aiming for.
进攻怎么打： · What beats it: 换防的一瞬间两名防守者挤在同一块地方。这时候真正空出来的往往不是切入者，而是那个本来要做掩护的人——他放弃掩护直接往篮下走就行。 · For one beat a switch has both defenders standing in the same place. The player who comes open is usually not the cutter but the one who was going to screen for him: he abandons it and goes to the rim.
容易混淆的动作 · Often confused with
反跑和哪些动作容易混？ · What is the Backdoor Cut often confused with?
下面这些动作和它长得像，但解决的问题不同。每一条只说那个决定性的区别。 · These look like it and solve a different problem. Each entry names the one difference that decides which is which.
传切是一套配合，反跑不是——它是所有贴防的通用答案，可以接在任何动作后面。所以传切要练时机，反跑要练的是眼睛：认出防守人的手已经伸进传球路线，比跑得快重要得多。 · A give and go is a play; a backdoor is not. It is the standard answer to being overplayed and it attaches to any action on the floor. Give and go is drilled for timing; the backdoor is drilled for eyes, because recognising that a hand is already in the passing lane matters far more than the speed of the cut.
反跑 vs 溜底线 · Backdoor Cut vs Baseline drift
溜底线是持球队友突破时，无球者沿底线移动到新的空位，目的是保持传球角度。反跑是主动攻击篮筐。一个在等球，一个在要球。 · A baseline drift happens while a teammate drives: the off-ball player slides along the baseline to keep a passing angle open. A backdoor attacks the rim on its own. One relocates to stay available, the other goes to score.
