1/9的文章，之前都挪不出時間翻 Watch: Thunder and the corner 3-point shot: what keeps going wrong? http://0rz.tw/6TXMq The corner 3-pointer is rapidly being established as one of the best shots in the game and more and more teams, like the Nets and Wizards, are using it against OKC. 底線三分球是球場上相當棒的出手點，而同時也有越來越多球隊─如巫師和籃網，使用這招來電雷霆。 The Thunder have started out 2013 by going 2-2. Those two losses have come in the most stomach-churning of ways. The first was a dispiriting home blowout loss to the Brooklyn Nets, and the second was on Monday night to the Wizards, which I trust needs no further qualification. 雷霆在今年的前四場比賽兩勝兩敗，這兩敗都是讓人胃部翻騰的敗仗。第一場是在主場被籃網電，第二場則是巫師隊。 One of the key elements in the Nets loss that I noticed was the performance of Joe Johnson. Johnson finished with a game high 33 points, but more importantly, finished 5-10 from 3-point range and a number of those shots came from one particular area on the court. Which area? It is the area that is unarguably one of the most efficient places to shoot. 幫助籃網贏球的最大功臣是Joe Johnson。Joe Johnson打出全場最高的33分，但更重要的是：三分球5-10，而且有不少是在同一點出手的。在哪裡呢？那一點可以說是得分最有效率的地方之一。 The corner 3-point shot. 底線三分。 Layups are great and free throws are sublime, but no shot has taken on more meaning in the past few years as the corner-3. Why? It is a shorter 3-point shot (22 feet), it stretches and spaces the floor like no other, and it is producing a specialized kind of shooter in the league, which makes the point production even more pronounced. How pronounced? According to the data from late last season, the corner-3 has become the greatest point producing shot in the game. 上籃很棒，罰球很壯觀，但是近年來意義都不及底線三分。為什麼？底線三分是距離最短的三分球(22呎)。這個位置在外面，跟其他地方也完全不一樣─它創造出特殊的射手，可以讓得分更為顯著。怎麼個顯著法？根據去年的數據，底線三分是最佳的得分地點。 Naturally, the best offensive teams and the best defensive teams in the league are going to be the ones who create and defend this shot the best. The teams and the coaches who put the most emphasis on taking and defending this shot are yielding dividends, and the teams who are not doing as well are being exploited. 自然而然的，最佳攻擊球隊與最佳防守球隊的重點都放在這裡(專投底線三分/專防底線三分)。任何注重這一塊的球隊或教練都會獲得好處，反之則會被擊垮。 Consider what NBA writer Zach Lowe reported a year ago: NBA作家Zach Lowe這麼寫： Limiting attempts seems to matter more than the percentage of corner threes opponents make. That’s not surprising. Lots of studies have found that limiting raw three-point attempts matters more than opponent three-point percentage. The raw number of corner-three attempts allowed last season correlated more strongly with both winning percentage and overall defensive rating than shooting percentage on corner threes, according to work by Maroun and McGuire. It also correlated more strongly with winning percentage than a team’s defensive rebounding rate and the rate at which a team forced turnovers. (In general, the correlation between defensive rebounding and winning percentage is typically stronger than it was last season, according to historical data.) 限制對手底線三分的「總出手數」比「命中率」更為重要。這個結果並不令人驚訝，很多研究指出對手「三分球」的總出手數比命中率更重要。在上一季之中，對手三分球出手數和球隊戰績、defensive rating(每一百波球權中的掉分)的正向關係比命中率更強烈。同時，和防守籃板的比率與製造對手失誤的能力比起來，角落三分的出手數跟戰績的關聯度也比較高。(不過去年球季中，防守籃板與戰績關聯度較以往高。) In general, the amount of corner threes a team allowed last season correlated strongly with winning percentage as a few other key factors have done so in prior years, including how often a team allows and earns free throws. 一般來說除了對手三分出手數之外還有一些細項和戰績也有強烈關係：罰球與對手罰球的數量。 Which brings us back to OKC. If you want a good measuring stick as to how well the Thunder defense is doing on any given night, pay close attention to how many open corner-3's they are giving up. Lowe had noted in the past that the Thunder were a poor corner-3 defending team, which is why they struggled so much early on trying to defend the Spurs in the regular season or the Heat in the Finals. OKC's defense fell apart once again in these two recent losses, so for the sake of some analysis, I took a look at the shots themselves and tried to break down both what the other team was trying to do as well as what the Thunder were doing wrong. 那就來談談雷霆吧，如果你想要知道雷霆任何一場的防守能力，仔細看看他們放掉多少底線三分。Lowe表示雷霆是一支很不會防守底線三分的球隊─這就是為什麼季後賽打馬刺打的這麼辛苦、打不贏熱火的一大原因。雷霆的防守在之前的兩場比賽敗仗中再度瓦解。為了加以分析，我試著分析對手要做的事情以及雷霆哪裡做錯了。 THUNDER VS NETS http://youtu.be/4uzPMzMG8W0

Play 1: Nets set up a double-baseline screen in order to free up Joe Johnson in the left corner. The Nets set a good screen, effectively sealing out 3 Thunder players with their 2 screeners. Thabo Sefolosha gamely tries to get through it but Johnson hits the open look. The Nets were setting the table for things to come. Play 1：籃網使用雙重掩護讓Joe Johnson成功溜到左邊底角。籃網的掩護做的很棒，用兩個掩護者擋住三個雷霆球員。Sefolosha勇敢的想闖出去，但是Johnson已經先一步到達，砍進空檔三分了。籃網佈局成功。 Play 2: I really like this play, not only because of the shot it produced, but because of how it gave Deron Williams so many options that the Thunder were forced to give up the long shot. Williams ran Reggie Jackson off a staggered set of baseline screens. While Jackson does his best to stay with Williams, once he is on Willams' hip the show is almost over. Williams actually passes up an easy drop-down pass to Kris Humphries, which likely would have produced a layup. Center Andray Blatche does a subtle but effective move by setting a back pick on Kevin Martin, changing Martin's momentum so that he cannot chase his man Keith Bogans as easily. Bogans smartly slides behind the back pick and gets a wide-open look. Play 2：我真的很喜歡這個play，不只是因為進球了─而是因為這次給Deron Williams 相當多的選擇，不得不讓雷霆放棄這顆三分。Williams在交錯的掩護之下甩開Reggie Jackson，雖然Reggie Jackson試著趕上Williams，但基本上當Williams屁股對著你的時候就完蛋了。Williams其實也可以選擇塞給Kris Humphries讓他上籃。不過這時候Andray Blatche做了不起眼但是產生效力的一步，他稍微擋了Kevin Martin的背一下，讓Martin 無法及時追上他要守的Keith Bogans。Bogans很聰明的從背面繞過去，得到了一個大空檔。 Play 3: The Nets are preying on Russell Westbrook's over-aggressiveness here in the way Westbrook likes to go over the top of baseline screens. Williams fakes as if he's going to cut to the baseline just as in Play 2, but instead makes a sharp V-cut and slides behind Blatche for the corner-3. Play 3：籃網抓住Russ過度積極這一點，讓他從底線掩護的後面繞過去。Williams假裝他要像Play 2那樣切到底線，但是他隨即做了V-cut，在Blatche的背後投了底線三分。 Play 4: The first 3 plays are well executed offensive sets, but this last one is more about the Thunder's poor transition defense and Westbrook's failure to recover to find his man. Westbrook is one of the fastest and most explosive guys on the court, yet it takes him a good 5 seconds to read the Nets' offensive set, find the open man in the corner (Johnson, the hottest shooter on the floor), and then jog over to him and casually contest the corner-3. 前三球都是籃網執行的很漂亮的戰術，不過Play 4是雷霆糟糕的快攻防守和Russ無法及時恢復狀況防守他自己的人所造成的結果。Russ是聯盟中最快、體能最勁暴的球員之一，但是他得花五秒才能看懂籃網的攻擊戰術之後才去找在底線有大空檔、當時最火熱的射手 Johnson─而且是很隨性的跑到底角隨便守一下。 On the other side of the coin, the Thunder have greatly improved as an offensive rebounding team this season, but as you can see in this case, it comes at the expense of having their guards, Westbrook and Martin, rotating to balance out the court in the event of a fast break the other way. After the shot goes up, Sefolosha is the only Thunder player above the free throw line, which makes for a fast break opportunity and allows Johnson to essentially sit in the corner of the court and wait for the pass to come. 在另一方面，雷霆這一季證明他們在進攻籃板方面有所進步，但是在這個例子中可以看出這讓他們的雙後衛(Russ和Martin)沒有辦法適時的輪轉，平衡場上的防守陣容來守住快攻。在那顆三分球出手之際，雷霆僅有Sefolosha站在罰球線之前─這讓籃網有個絕佳的快攻機會，同時讓Johnson能在底角輕鬆的等球。 Play 5: This is another well designed play, but the Thunder hurt themselves by making two fundamental errors. The first is when Deron Williams sets a screen for Gerald Wallace on the baseline, which allows Wallace to run straight to the rim. Westbrook, who is guarding Williams, does not switch with Martin, who is guarding Wallace. By not switching, Wallace catches the ball clean under the rim and both Martin and Westbrook are out of position. Wallace was a bit too far under the rim, but probably could have landed and finished had he wanted to. However, once again the Nets target the corner-3 and Wallace throws a great touch-pass to Johnson. Play 5：這是另一個設計的很好的play，但是雷霆自己也犯下了兩個既基本又致命的錯誤。其一，當Williams在底線掩護Gerald Wallace、讓Wallace能直接跑到籃下時，負責守 Williams的Russ沒有和守Wallace的Martin交換防守。因此，Wallace輕鬆的在籃底接到，而Russ和Martin的位置則是都跑掉了。Wallace離籃框有點遠，不過他要直接進去得分也是沒問題的。而籃網再次選擇底線三分，Wallace快傳給Johnson。 The second fundamental error made is when Sefolosha leaves his man Johnson to help out with Wallace. The standby rule in help defense is, never leave your man to help out on defense if your man is one pass away from the ball. Here, Sefolosha does just that and leaves the game's high scorer to hit another corner-3. 第二個錯誤，則是Sefolosha放掉Johnson跑去協防Wallace。協防的基本要件是：如果對方能直接傳球到你守的人手上，千萬不要跑去協防。這一次，Sefolosha讓全場得分最高的Johnson丟進三分球。 + To be fair to the Thunder, a number of these plays were really well executed and produced some great looks.However, there is a bigger issue at play. The bigger issue is the fact that the Nets CLEARLY game-planned to make not just the 3-point shot, but specifically the left side corner-3, an essential part of their offense in order to beat the Thunder. They knew OKC struggles in guarding that spot and so Brooklyn exploited it again and again. Smart teams like the Spurs, Heat, and Clippers are going to make the Thunder pay unless they figure out a better way to shore up this defensive weakness, which as was established above, is the best point-producing shot in the game. 說句公道話，這些都是籃網執行的非常漂亮的play，在空檔之下也成功砍進分數。不過這代表著更大的危機─籃網確確實實的藉著「計畫」取得投三分的機會，尤其左邊底角的三分球更是進攻的主軸。籃網知道雷霆在這個部分表現不佳，所以他們一次又一次的在左邊底角轟炸雷霆。聰明的球隊，諸如熱火、馬刺、快艇等隊在雷霆想出方法之前都會讓雷霆付出代價。這個防守弱點可是最容易飆分的地方。 THUNDER VS WIZARDS http://youtu.be/-2L2abjVQbM

If the Nets loss was a lesson on how a good offense knows how to exploit a fallible defense, the loss to the Wizards was a lesson on what happens when defensive malaise allows the 2nd worst 3-point shooting team in the league to make 10-18 from long range. 如果說輸給的籃網這場比賽代表著進攻強隊痛宰有問題的防守，那麼，輸給巫師的這場敗仗告訴我們，就算是三分球第二差的巫師，也能在外線10-18。 Play 1: The Wizards run a basic high pick and roll. Westbrook and Serge Ibaka actually do a very good job of trapping it, turning A.J. Price away from the rim, too far too shoot, and with only one easy passing lane back up to the top of the key. However, Ibaka, the big man who came off the screen to cut off Price's drive, suddenly runs away from his strong defensive position, allowing Price to penetrate and then kick out to Martell Webster for the corner-3. Ordinarily, the big man who 'shows' on the PnR is supposed to rotate back to his own man after the drive is cut off, but the problem here is that Westbrook was already trailing the play and had no defensive position on Price. When Ibaka left his position, Price was effectively guarded by nobody and he penetrated until the corner pass opened up. On this play, Ibaka needed to stay where he was and he and Westbrook could have either held the trap or they could have switched the screen completely. Play 1：巫師要執行高位的pick and roll，這時Russ和Ibaka的包夾非常的漂亮，讓A.J. Price無法攻擊籃框、無法直接投球(太遠)，只能把球傳回弧頂。不過突破掩護的Ibaka為了截掉Price的切入，竟然離開了很好的防守位置，讓Price成功切進去並把球丟給人在底角的Martell Webster。照理說防守pick and roll的大個子在切入被擋下來之後應該去守自己的人─但是這一次的問題是Russ並沒有趕上這個play，沒有辦法擋住Price。當Ibaka 一離開，Price等於是沒人防守了─這時只需要切進去，等待傳到底角的時機出現即可。在這個play之中，Ibaka應該留在他原本的位置，而他和Russ要嘛就是維持包夾，要嘛就是交換掩護的位置。 Play 2: Gambling in the back-court. Without a concerted and organized effort to press, this is almost always a guaranteed bad idea in the NBA. Even the most basic of ball fakes creates a 5 on 4 opportunity going the other way. Play 2：後場的賭博式防守。在缺乏專注力與組織性的壓迫之下，這可以說是最糟糕的作法。就算是最基本的假動作也能創造出5打4的機會。 Play 3: We've seen this one plenty of times this season. I would surmise that Westbrook is giving up several of these kinds of shots every game because his opponents now know that if they run hard after Westbrook misses a shot, they are going to get a wide open look. Even worse is that they're running straight to the spot that now everyone seems to know the Thunder struggle to defend. Even the Wizards. Play 3：這一季蠻常看到的，我猜Russ每場比賽都會放掉(這類型的)好幾球，因為對手知道只要Russ沒進，趕快跑就對了─只要跑出去就能獲得空檔。最糟的是他們會直接跑到那個神秘的地方─那個雷霆守不住的神祕地點。 Even the Wizards. *** The issues highlighted above are a blend of good scheming by the opposition, a lack of an aggressive posture defensively, and unfortunately, a little bit of laziness. Each issue will need to be addressed however because the Thunder are going to face plenty of opportunities in the remainder of this season to learn to deal with this shot. I don't think OKC or any team in the league can simply decide to play the corner-3 straight up anymore; teams have to start taking the posture that they have to take it away completely if they want to have a sound defensive game plan. 這個問題顯示出對手的高超計策、雷霆缺乏積極性的防守以及懶惰。這些問題都得被解決，不過雷霆在接下來的球賽中會試著解決這個位置。我不認為雷霆或任何球隊能直接下決定直線增加投底線三分的次數。如果他們想要有個很棒的防守計畫，他們必須扼殺這個位置的攻擊機會。 An oft-repeated basketball defensive slogan is, "Protect the rim." It is time the Thunder add to that the phrase, "And take away the corner-3." 我們常常聽到這個口號："Protect the rim."，不過雷霆應該加上這一句： "And take away the corner-3." -- "HARD WORK BEATS TALENT WHEN TALENT FAILS TO WORK HARD." -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 122.117.20.246
