這是對小牛後的防守拆解文，可對照圖片，很容易了解火箭的防守問題 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. 火箭雖然進攻名列前茅，但都被防守抵消了。根據NBA官網數據，他們本季防守效率排名 23，2/1日之後更只有27名。2/1算起，他們讓對手平均每100次進攻得109.3分，只比拓荒者、國王和山貓好。 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. 一般人很容易將問題歸咎於他們喜歡用小個子拉開空間進攻的策略，但從對小牛一戰可看出其實和身高無關，火箭的防守主要有兩大問題。 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，只盯著球。火箭外圍防守員有個很糟糕的壞習慣，常在協防另一側的對手時丟掉自己對位的人。初級班教練就教過要同時盯著球和人，但是火箭的側翼防守者卻總是只看著球。 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開賽1分鐘時哈登的防守問題。小牛投了一記三分但沒有進，哈登離開對位的人去幫忙搶籃板。 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. 但看看他沒搶到籃板時發生什麼事。哈登只是呆站在罰球線附近盯著球，而這時Marion 已經從他面前切進去上籃。 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. 當然，哈登看守的人並不在禁區。但如果他要站在罰球線附近，就要幫忙防止有人像 Marion這樣切入，否則他就只是個站在三不管地帶看戲的觀眾。 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. 哈登不是火箭隊裡唯一只看球的人。以下是第二節時，Parsons沒看好Nowitzki，讓他從後面切入。 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. 這次進攻是從Darren Collison and Nowitzki檔拆開始。Parsons沒有卡好，讓Collison 溜到角落，但這還不致於造成太大傷害。接著D-Mo過來攔截Collison，理論上這時 Parsons應該可以趕回Nowitzki身邊，遏止住這個小牛的頭號威脅。但是Parsons沒有，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傳給Marion，Parsons還在死盯著球。他沒有選擇回去守Nowitzki，而是盯住Marion，即使D-Mo已經回去封住Marion的切入路線仍然不改。 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. 這麼一來就讓Nowitzki有了從後面切入的空檔。很妙的一點是這時Parsons突然後退到 Nowitzki切入的路徑上，但並沒有斷球，因為他根本沒發現Nowitzki人就在那裡。結果就是這樣： 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. 這是一個問題。另一個問題更麻煩：火箭球員老是有協防過頭的傾向。他們似乎一直無法找到弱邊防守的平衡點。不是在場上睡著了，讓對位者出現空檔，不然就是很沒必要地全擠在球旁，讓出傳球空檔。 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. 這裡又是一個跟Parsons有關的範例。小牛檔拆後火箭換防，讓林書豪對上Nowitzki。這一來當然不太妙，但是要來協防一定得小心。過來得太快會讓Nowtizki看到整個空間，拆解掉防守陣勢。小牛弱邊兩位射手的站位很完美，可防止萬一包夾發生。火箭必須要看到這一點，不能輕易漏陷。 http://ppt.cc/8WJV 結果膩看看，Parsons做了什麼。 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都還沒有動作前，他就過來包夾，結果反而危及團隊的防守。哈登被迫必須一個人守弱邊兩個站位完美的射手，根本不可能守得好。現在Nowitzki只需要把球傳給Mayo ，他再傳給角落裡的Collison就好了。這是對付包夾最標準的破解之道。 http://ppt.cc/7i3V Collison misses the wide-open shot, but that's still bad Rockets defense. Collison沒把握好這個大空檔，但這仍然是火箭一次失敗的防守。 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. 第四節還有一個例子。在這球之前Carter已經連中2記三分球。防守時若非絕對必要，千萬不可以放掉手感正好的人去協防。尤其這次Mayo切入時的防守陣勢，Delfino其實不需要去協防。 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，哈登有跟著Mayo。再者，離開你的對位球員時一定要小心持球者是不是能輕易傳給他。好的防守球隊會盡量避免協防一次傳導可到的位置。如果Delfino只是跨出一步去減緩Mayo切入的速度，而不是整個飛身過去協防就合理得多。但是Delfino 離太遠了，讓 Carter 出現空檔，射出了他的第三顆三分球。 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. 除了這些問題，火箭有一個主要的缺點，他們在弱邊防守上缺乏良好的團隊溝通。以下這一球總結了火箭許多問題。第一球時，防守從Elton Brand在禁區持球時，Delfino 讓 Carter從他的背後切入開始崩解。 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一定是以為在籃底的Garcia 當時盯住Carter了。但其實Garcia是想要從Brand 背後偷溜過去形成怪怪的包夾。 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. 為了因應Garcia的包夾，Crowder跑到底角，造成三個火箭球員防守兩位小牛球員的情形，因此Brand出現傳球空檔傳給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. 接著Crowder再傳給Collison，這時Garcia再火上加油。沒腦的包夾已經讓他偏離該有的位置，讓角落裡的Patrick Beverly被迫一人防守Crowder and Collison。現在Garcia又在Beverly已經跑向Collison的情形下，跟著過去做重複的事。 http://ppt.cc/W1a0 That leads to an open Crowder three that he swishes. 結果就造成Crowder出現空檔，三分進帳。 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. 現在的NBA，即使打小個陣容也可以有嚴密的防守。當然，這樣籃板會少一點，禁區被會大個子蹂躪。但是現在有這麼多隊打檔拆，玩拉開空間的策略，有一套完善的戰術加上良好的協防概念還是足以和敵隊抗衡。但是像上面所顯示的，火箭就是缺少上述條件。不管你要怪球員、教練還是任何人，總之這情形一定得改善。否則未來仍然還是支只會耍花招騙騙人的隊伍。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 119.14.83.24
