这是对小牛後的防守拆解文，可对照图片，很容易了解火箭的防守问题 http://ppt.cc/gutB The Houston Rockets have serious defensive problems By Mike Prada on Mar 7 2013 The Houston Rockets have electrified the league with a high-powered offense, but until they significantly improve their defense, they run the risk of missing the playoffs. We break down just how bad Houston's weakside D really is. The Western Conference playoff race has tightened up considerably. Wednesday's thrilling win over the New Orleans Hornets pulled the Los Angeles Lakers to within 1½ games of the playoffs. The Lakers have played relatively well recently, of course, but they needed help in getting back into the race. Recently, they've received that help from the three teams ahead of them in the race: the Houston Rockets, Utah Jazz and Golden State Warriors. We talked about the Jazz's woes Tuesday. Now, let's talk about the Rockets. Specifically, their leaky defense that could cause them to drop out of the playoff picture. Led by James Harden and a plethora of outside shooters, the Rockets have one of the league's best offenses, but their defense gives it all back. They're ranked 23rd in defensive efficiency for the season and 27th since Feb. 1, via NBA.com's media stats page. Since that date, they've allowed opponents to score an average of 109.3 points per 100 possessions. Only Portland, Sacramento and Charlotte have been worse. 火箭虽然进攻名列前茅，但都被防守抵消了。根据NBA官网数据，他们本季防守效率排名 23，2/1日之後更只有27名。2/1算起，他们让对手平均每100次进攻得109.3分，只比拓荒 者、国王和山猫好。 It's tempting to blame this decline on the team's wide-open style of play, which puts smaller players on the court to spread the floor offensively. However, in watching the Rockets' latest costly loss, a 112-108 defeat in Dallas Wednesday, it's clear the Rockets' defense suffers from two major problems that have nothing to do with size. 一般人很容易将问题归咎於他们喜欢用小个子拉开空间进攻的策略，但从对小牛一战可看 出其实和身高无关，火箭的防守主要有两大问题。 The first: ball watching. The Rockets' perimeter defenders have an awful habit of losing track of their man when they are defending someone on the opposite side. Your grade-school coach always tells you to see balland man. Too often, the Rockets' wing defenders only see ball. 第一，只盯着球。火箭外围防守员有个很糟糕的坏习惯，常在协防另一侧的对手时丢掉自 己对位的人。初级班教练就教过要同时盯着球和人，但是火箭的侧翼防守者却总是只看着 球。 Here's one breakdown by Harden in the first minute of Wednesday's game. The Mavericks have launched a three-pointer in transition that missed, and Harden drops off his man to help on the glass. 以下逐步拆解3/7开赛1分钟时哈登的防守问题。小牛投了一记三分但没有进，哈登离开对 位的人去帮忙抢篮板。 http://ppt.cc/opwz But watch what happens once Harden doesn't get the rebound. He just sits in the lane watching the ball, right as Shawn Marion cuts in front of him for a layup. 但看看他没抢到篮板时发生什麽事。哈登只是呆站在罚球线附近盯着球，而这时Marion 已经从他面前切进去上篮。 http://ppt.cc/FTKU http://ppt.cc/qfy4 Harden's man isn't around the paint, to be fair, but if Harden is going to drop down to the lane, he has to actually help against a cutter like Marion. Otherwise, he's just a spectator in no-man's land. 当然，哈登看守的人并不在禁区。但如果他要站在罚球线附近，就要帮忙防止有人像 Marion这样切入，否则他就只是个站在三不管地带看戏的观众。 Harden isn't the only Rocket prone to ball-watching, though. Watch asChandler Parsons loses sight of Dirk Nowitzki on a backcut in the second quarter. 哈登不是火箭队里唯一只看球的人。以下是第二节时，Parsons没看好Nowitzki，让他从 後面切入。 The play begins with a pick and roll between Darren Collison and Nowitzki. Parsons doesn't trap well, allowing Collison to turn the corner, but it shouldn't matter too much. Donatas Motiejunas steps up to contain Collison, which should theoretically allow Parsons to scurry back to Nowitzki and contain the Mavericks' top threat. Instead, Parsons' eyes are addicted to the ball. 这次进攻是从Darren Collison and Nowitzki档拆开始。Parsons没有卡好，让Collison 溜到角落，但这还不致於造成太大伤害。接着D-Mo过来拦截Collison，理论上这时 Parsons应该可以赶回Nowitzki身边，遏止住这个小牛的头号威胁。 但是Parsons没有，他的眼睛完全黏在球上。 http://ppt.cc/BvM_ This addiction doesn't stop once Collison drops it off to Marion. Rather than recover to Nowitzki, Parsons stares at Marion, even as Motiejunas recovers to close out on Marion's drive. 一直到Collison传给Marion，Parsons还在死盯着球。他没有选择回去守Nowitzki，而是 盯住Marion，即使D-Mo已经回去封住Marion的切入路线仍然不改。 http://ppt.cc/lh0q This opens Nowitzki's backcut. Amazingly, Parsons retreats right into Nowitzki's cut accidentally and still can't intercept the pass because he doesn't realize Nowitzki is there. This is the end result. 这麽一来就让Nowitzki有了从後面切入的空档。很妙的一点是这时Parsons突然後退到 Nowitzki切入的路径上，但并没有断球，因为他根本没发现Nowitzki人就在那里。结果就 是这样： http://ppt.cc/cR66 That's one issue. The other, more perplexing one: the Rockets' tendency to over help. It's like they can't find a happy medium with their weakside defense. Either they fall asleep and leave guys open, or they swarm the ball unnecessarily and open up easy passing lanes. 这是一个问题。另一个问题更麻烦：火箭球员老是有协防过头的倾向。他们似乎一直无法 找到弱边防守的平衡点。不是在场上睡着了，让对位者出现空档，不然就是很没必要地全 挤在球旁，让出传球空档。 Here's an example that involves Parsons. The Mavericks force a switch on a pick and roll, leaving Jeremy Lin to guard Nowitzki at the elbow. This is not an ideal situation, of course, but you have to be careful when providing help. If you help too soon, Nowtizki can see the entire floor and pick your defense apart. The Mavericks have perfectly positioned two shooters on the weakside in the event of a double team, and the Rockets have to recognize that and not tip their hand with their coverages. 这里又是一个跟Parsons有关的范例。小牛档拆後火箭换防，让林书豪对上Nowitzki。这 一来当然不太妙，但是要来协防一定得小心。过来得太快会让Nowtizki看到整个空间，拆 解掉防守阵势。小牛弱边两位射手的站位很完美，可防止万一包夹发生。火箭必须要看到 这一点，不能轻易漏陷。 http://ppt.cc/8WJV 结果腻看看，Parsons做了什麽。 Alas, they do. Look at what Parsons does here. http://ppt.cc/r5L9 By doubling Nowitzki before he even makes a move, Parsons has compromised the Rockets' defense. He's forced Harden to cover two perfectly-spaced shooters on the weakside, and nobody can do that properly. All Nowitzki has to do is swing the ball to O.J. Mayo, who can then swing it to Collison in the corner. That's the easiest double-team read in the book. 在Nowitzki都还没有动作前，他就过来包夹，结果反而危及团队的防守。哈登被迫必须一 个人守弱边两个站位完美的射手，根本不可能守得好。现在Nowitzki只需要把球传给Mayo ，他再传给角落里的Collison就好了。这是对付包夹最标准的破解之道。 http://ppt.cc/7i3V Collison misses the wide-open shot, but that's still bad Rockets defense. Collison没把握好这个大空档，但这仍然是火箭一次失败的防守。 Here's another example from the fourth quarter. Some context: before this play, Vince Carter hit two consecutive open three-pointers. As a defense, you want to be careful to help off someone that hot unless it's totally necessary. Given the way this drive by Mayo is being defended, it probably isn't totally necessary for Carlos Delfino to help like this. 第四节还有一个例子。在这球之前Carter已经连中2记三分球。防守时若非绝对必要 ，千万不可以放掉手感正好的人去协防。尤其这次Mayo切入时的防守阵势，Delfino其实 不需要去协防。 http://ppt.cc/fPi~ For one thing, Harden is staying right with Mayo. For another, you always want to be careful when you drift off a guy that the ball-handler can easily feed. This concept, known as helping "one pass away," is something most good defensive teams try to avoid. Had Delfino taken a single step off Carter to slow Mayo's penetration rather than helping all the way -- a motion known as "stunting" -- it would have made more sense. Instead, Delfino slid over way too far and opened up Carter for his third three-pointer of the game. 第一，哈登有跟着Mayo。再者，离开你的对位球员时一定要小心持球者是不是能轻易传给 他。好的防守球队会尽量避免协防一次传导可到的位置。如果Delfino只是跨出一步去减 缓Mayo切入的速度，而不是整个飞身过去协防就合理得多。但是Delfino 离太远了，让 Carter 出现空档，射出了他的第三颗三分球。 http://ppt.cc/h~a4 So, you have lots of problems at play. The larger theme: The Rockets are a team that fails to communicate weakside defense properly. This one play from the second quarter sums up a lot of Houston's problems. As you can see in this first shot, things start to break down when Delfino lets Carter cut backdoor on him while Elton Brand has the ball in the post. 除了这些问题，火箭有一个主要的缺点，他们在弱边防守上缺乏良好的团队沟通。以下这 一球总结了火箭许多问题。第一球时，防守从Elton Brand在禁区持球时，Delfino 让 Carter从他的背後切入开始崩解。 http://ppt.cc/JN_A Delfino must think that Francisco Garcia, pictured under the hoop, can pick up Carter for a second. Instead, Garcia is trying to sneak behind Brand on a weird double team. Delfino一定是以为在篮底的Garcia 当时盯住Carter了。但其实Garcia是想要从Brand 背後偷溜过去形成怪怪的包夹。 http://ppt.cc/1-5F In response to Garcia's double, Jae Crowder drifts to the corner. That sets up a situation where three Rockets are guarding two Mavericks, giving Brand an easy passing lane to Crowder. 为了因应Garcia的包夹，Crowder跑到底角，造成三个火箭球员防守两位小牛球员的情形 ，因此Brand出现传球空档传给Crowder。 http://ppt.cc/r8pN Crowder then swings the ball to Collison, and Garcia makes matters worse. Garcia has already put himself well out of position with his ill-advised double team, and now he runs out on Collison even though Patrick Beverly, the man in the corner that's forced to defend both Crowder and Collison, does the same. 接着Crowder再传给Collison，这时Garcia再火上加油。没脑的包夹已经让他偏离该有的 位置，让角落里的Patrick Beverly被迫一人防守Crowder and Collison。现在Garcia又 在Beverly已经跑向Collison的情形下，跟着过去做重复的事。 http://ppt.cc/W1a0 That leads to an open Crowder three that he swishes. 结果就造成Crowder出现空档，三分进帐。 http://ppt.cc/R1MB *** We've reached an era of the NBA where you can play sound defense while going small. Sure, you give up a bit on the boards, and bigger teams can pound you inside, but given the way so many clubs run pick and roll and spread the floor, a sound strategy with good help defensive concepts should allow you to compete. But as demonstrated above, the Rockets lack this kind of direction. Blame the players, the coach or whomever else you want, but that has to change. Otherwise, the Rockets really will continue to be a gimmick team in the future. 现在的NBA，即使打小个阵容也可以有严密的防守。当然，这样篮板会少一点，禁区被会 大个子蹂躏。但是现在有这麽多队打档拆，玩拉开空间的策略，有一套完善的战术加上良 好的协防概念还是足以和敌队抗衡。但是像上面所显示的，火箭就是缺少上述条件。不 管你要怪球员、教练还是任何人，总之这情形一定得改善。否则未来仍然还是支只会耍花 招骗骗人的队伍。 --
