Lakers’ “1-2″ Screen & Roll
湖人后卫双雄挡拆战术
During the early going of the fourth quarter, the Lakers offense was really struggling. They stopped going inside, they stopped moving the ball, and they stopped spacing the floor. It basically turned into a “get Kobe the ball and watch” game。
第四节比赛开始一段时间里湖人的进攻陷入停滞。他们停止对内线的攻击，没有华丽运转球，没有通过无球跑动拖长对方防线。几乎变成把球交给科比然后站着看好戏的局面。
However, with about 5:30 minutes left and a four point lead, the Lakers came across a play that started working well for them, and that was the “1-2″ Screen & Roll. The “1-2″ Screen & Roll is simply your point guard (or the “1″) comes off of a screen set by the shooting guard (or the “2″).
但是，第四节剩下差不多5分半钟湖人领先4分时，湖人执行了效果不错的战术。这就是1、2号位之间挡拆战术（这是得分后卫替控球后卫掩护的简单战术）下面间谍照演示：
After the inbounds play, the ball gets swung around to Derek Fisher on the top of the key. Kobe Bryant, who was ISO’d up on the opposite block, now comes up to set a screen for Fisher.
开出界外球后，湖人经过几次传球把球交到了弧顶老咸鱼手里，科比这时候卡在阿伦前面（可以接球后单挑阿伦），但是他出人意料跑上去替咸鱼掩护。
As we get to the point of contact for the screen, the Celtics have a few options. They could switch the screen, but that leaves Rajon Rondo covering Kobe Bryant, and that is a mismatch. You could double team the man coming off of the screen, but that leaves Kobe open. Finally, you could have Rondo fight over the top and have Ray Allen hedge. That is what the Celtics choose to do here.
应对掩护，凯子有几个防守策略的选择，他们可以换防，但这就变成狼多错对防科比（科比身高优势可跳投得分）。可以包夹咸鱼，但这会让科比处于无人防守状态（后果惨无人道）。最后可以是雷阿伦先过来阻挡一下咸鱼的进攻路线，让狼多有时间穿过科比的掩护防咸鱼，阿伦恢复防守科比。
Ray Allen shows and immediately gets back to Kobe, expecting to have Rondo fight over the top of the screen and getting back to Fisher. However, Rondo gets caught up on this particular screen, and now Paul Pierce has to make it all the way across the court (because there is really good floor spacing) to try and close out on Fisher’s shot attempt.
阿伦阻挡一下费沙后很快回防科比，希望狼多能穿过掩护回防费沙，但是狼多被科比很好的掩护卡住了，皮尔斯从较远处屁颠屁颠赶快扑过来补防（因为湖人很好地拉长凯子防线，清空了禁区）
Pierce doesn’t get there in time and Fisher is able to knock down the jumper.
皮尔斯为时已晚后悔莫及，费沙射入稳定军心的一球。
