NBA在乔丹退役后通过修改规则让规则尺度更利于外线，这是nba官方自己都承认的事，如果你觉得你比规则制定者更懂球那你明说好了在你了解NBA规则变化史之前先了解一下事实，事实就是NBA官方都承认了乔丹退役后为了造出第二个乔丹，不断修改规则让比赛更有利于外线球员。直接给你贴个官方的采访你想知道为何比赛风格会改变， NBA官方告诉你，他们制定规则，他们清楚改规则后的风格变化当时制定规则联盟副总裁斯图杰克逊的采访NBA.com: Since the hand-checking rule was interpreted differently beginning in the 2004-05 season, the game has opened up. Players are penetrating and the floor is spread. As a result, scoring has risen every season. Was this anticipated back in 2004? SJ: No. The scoring increase was not our goal. Our objective was to allow for more offensive freedom by not allowing defenders to hand-, forearm- or body-check ball handlers. By doing so, we encouraged more dribble penetration. As players penetrated more, it produced higher quality shots for the ball handler as well as shots for teammates on passes back out to perimeter. When NBA players get higher quality shots -- having more time to shoot -- they tend to make more of them. 提问：自从04~05年修改规则 ，比赛变的开放，球员们开放式的突破，结果来说，分数每年都在增加，这些在04年都被预计到了么？ 回答：不，增加得分并不是我们的目的。我们的目的在通过禁止球员用手，前臂，身体顶防运球者从而给于进攻更多的自由。通过这些，我们鼓励更多的突破。而当球员更多的突破，就能给运球者回传给外线的射手提供更高质量的投篮机会。当球员们得到更高质量的投篮以及有更多的时间准备投篮，他们会投进更多。 NBA.com: Shooting percentages have risen since 2004-05 regardless of location -- at-the-rim shots, short- and deep-mid range and 3-pointers. Does this surprise you, especially the higher percentages from 3-point range? SJ: It doesn't. With the rule and interpretation changes, it has become more difficult for defenders to defend penetration, cover the entire floor on defensive rotations and recover to shooters. This has provided more time for shooters to ready themselves for quality shots. With more dribble penetration, ball handlers are getting more opportunities at the rim. Additionally, teams now realize the 3-point shot is a great competitive equalizer, so they are taking more; they have improved their skill level on threes and are making them at a higher rate. 提问：自从修改规则后，篮下，近距离投篮和三分的命中率都提升了。这是否让你感到惊讶，特别是 三分命中率。 回答：不，随着规则的改变，防守突破要难的多，防守轮转到位也困难的多。这让射手有更多的时间调整投篮高质量的完成他们。随着更多的突破，控球手们获得更多攻击篮下的机会。而球队现在意识到三分是个追分利器，所以他们投的更多了。他们提高了三分。 NBA.com: The number of 3-point attempts has risen since the 2004-05 season, more so than the mid-range shots. Is this a positive development? SJ: It depends on your perspective. We feel the 3-point shot has been an exciting play for our game and has put a premium on having skill players with an all-around game. NBA.com: Doesn't the wide-open style benefit certain types of players? For example, wing players vs. frontcourt players? SJ: The benefits of an open game are not limited to just perimeter players. An open game can benefit a post player as well. Remember, if the players are spaced wider and using more of the court, then defenses have to play those players closely because they're good shooters. The style actually serves to open up the middle of the floor. If a team has an effective post player, he would have more room to operate in the post. 提问：现在的风格是否让某些特型球员受益？举个例子，侧翼和前场球员。 回答：它不只让外线球员受益。现在的比赛也让低位球员同样受易。记得么，如果球员空间拉开更大，更利用球场空间。防守就会扩的更外，因为他们是好的射手。这样就会让中路空间更大。如果一只球队有个好的低位选手，他就有更多的空间在低位单打。 NBA.com: From an Xs and Os perspective, how have coaches adjusted to a more wide-open game? What have they done differently? SJ: Coaches have utilized more space on the floor so to create more room for dribble penetration, two-man pick-and-roll basketball and dribble exchanges on the perimeter. But to do that, they have attempted to place the right personnel on the floor -- more shooters and ball handlers that require defenses to play those players on the perimeter. 提问：在现在的环境下，教练们会怎么样调整？他们现在做的有哪些不同 回答：教练已经开始利用现在规则上能拉开更多的空间的优势设计更多更好拉开空间的突破战术，2人当差。不过要执行这些，他们必须有正确的配置-更多的射手和控球者。 NBA官方说的很清楚，削弱外线对抗，让突破更自由导致轮转更难，需要更多补，而更多补又会造成更多外线空档，难以轮转，给外线投篮巨大空档，为了利用好这种突破+巨大空档的优势，所以在配置上更多用三分射手，同时在战术上更多的用挡拆。 这么一来二去，三分射手又反过来回馈单打手和突破手，让他们有更多的1对1和空间。 这才是前因后果和逻辑原因，给外线打法开绿灯，是一切的源头和开始。 而为何给外线开绿灯，就是乔丹在90年代的成功，让nba想持续让这种外线成功持续留在nba，持续吸引球迷，持续维持巨大的市场和经济利益。
