Hornets Guards ---- Passing 黄蜂後卫：传球数据评析 http://www.atthehive.com/2015/7/30/9072079/hornets-guards-passing 感谢板友eileen86分享，有翻错请指正。图片我另外抓出来放，便於手机直接看图。 First time posting here. Kind of just play with our player stats from last season, and see what I get. So the first set of numbers I was looking at are their assists vs. touches/game. (players included are guards and small forwards who played at least 5 games last season and with minimum 10 min/game PT). 首波！让我们先来看看黄蜂的每场比赛助攻/持球次数比，比较对象为上季至少出赛5场， 且每场至少10分钟的後卫和小前锋。 http://tinyurl.com/pffpytj (图一) In general, the more touches a player had, the higher assist they will generat. The solid line indicated the league average assist number player generated with their touches. Each circle represent a player, with red ones are our currently players and blue ones were ex-Hornets played last season. 基本上持球次数愈多，助攻愈多。实线表示联盟平均助攻数和持球次数间的关系。 每一圆圈代表一位选手，红色为黄蜂目前球员，蓝色为已离队的蜂蜂。 Players located above the solid line are above league average in generating assists with their numbers of touches , and players located below the solid line would be considered under league average. 实线上方为助攻数/持球次数比数值方面高於联盟平均者，实线下方的球员则低於联盟平 均。 High lighted yellow are players who touches the ball a lot during a game, and generates lots of assist. And you will find very familiar names in that cluster: Chris Paul, John Wall, Stephen Currry, LeBron James, Russell Westbrook, Rickey Rubio, Ty Lawson, Reggie Jackson. Interesting to see Michael Carter-Williams in Sixers (labeled green) really only had average capability in generate assists, but he was leading the league in touches/game, kind of wondering whether Sixers were just simply trying to boost his numbers. 黄色醒目为一场比赛中持球次数多且助攻数多者，可以在这一块发现许多知名球星赫然在 列：CP3、姜墙、咖哩、LBJ、西河、卢小比、泰劳、Reggie Jackson等。值得注意的是绿 标为七六人的MCW，他助攻方面仅在平均值范围内，但每场比赛持球次数居联盟之冠，有 点好奇是否因为七六人只是想让他刷数据 Out of 6 players who had greater than 90 touches per game, Kemba Walker had the lowest assist number, by a big margin. Kemba had 0.3 ast more per game than Batum with 30 more touches. With similar touches per game, Westbrook (labeled orange in the graph) has 8.6 APG, which is 3.5 more than Walker's 5.1 APG. So why is that, is Kemba Walker a ball hog? I like to use %pass to sort out ball hogs. I calculated %pass = pass per game/touches per game*100%. That is a good indication on chances a player tend to pass out the ball when they touch it. 每场比赛中超过90次持球者有6位，其中Kemba Walker的助攻数远低於其他人。Kemba每场 较Batum多0.3次助攻而已，但持球次数多了30次。图中橘色点点是西河，他和坎巴的每场 比赛持其次数相近，助攻数却达8.6，高於坎巴的5.1。 所以这代表甚麽？我们可以说坎巴是球霸吗？ 我偏好用传球%来找出球霸们。我的计算方式是每场比赛传球次数/持球次数*100%，这项 数据可以清楚表示球员一球在手时的传球倾向。 http://tinyurl.com/oy39os8 (图二) The solid line is the league average of all the players who played more than 5 games last season and with > 10 min PT. And the dotted line were indicating 1*SD from the average. 实线为联盟平均值，计算对象为上季出场至少5场且每场至少10分钟的所有球员。虚线则 距平均值有1个标准差(1*SD from the average，意思不确定，求解？) I found this view is a good way to cluster super passer from ball stoppers. Players with super high pass percentages tend to cluster with players who promote ball movement, but don't really like to shoot the ball. And players who have low percentage of passes tend to be volume shooters who likes to shoot everything. And I did not realize Nick Young pass less than 50% when he touches the ball. 个人认为这张图清楚分出了球霸和擅於传球者。高传球率的球员们容易推进球，但不太 会真的出手。低传球率的球员则出手率高，就喜欢射射射。 然後我以前还不太懂尼克羊持球时的传球率低於50%。 http://tinyurl.com/pyzl9k3 (图三) So when we look at the players on Hornets team, first thing I noticed is that Batum passes a lot, and that also is consistent with his low USG rate of only 14.7% last season.To my surprise, Kemba Walker not only not clustered with non-passer group, he actually had above average in terms of willingness to pass the ball. Lin and Mo Williams sit right at the league average there. Then the question is, why Kemba had low assist when he is a willing passer? 上面这张是黄蜂球员的数据。我注意到的是Batum传球率高，这也相符於他上季的低USG， 使用率仅14.7%，而出乎意料之外的是，坎巴没有位於不传球的球员群之中，全队传球意 愿也高於平均。 Lin和Mo则差不多等於联盟平均值。 问题来了：坎巴传球意愿高，怎麽会助攻那麽低呢？ There are two kinds of passes. 1) you use your court vision or play making skills, and you hit an open man, then that pass results in an assist opportunity or hockey assist. 2) you don't have a good look so you just get rid of the rock either leave the work to your teammates or you reset and then demand the ball later on, so that's just a simple pass. 传球有两种： (1) 运用全场视野或战术技巧，找到空档球员，那麽这传球就是一项助攻机会或是接即投 的助攻机会(不确定hockey assist，求解？) (2) 不需要太好的传球视野，而只是为了摆脱纠缠，传球给队友後再让他传回来，这样就 只是单纯的传球(这句也不太确定，求解？)。 So I calculated Assist opportunity percentage = (assist opportunity + secondary assist per game)/ pass *100% This number is a good indication on how active a player is looking for helping their teammates to score. 因此我计算了助攻机会%，计算方式为(每场比赛助攻机会+二次助攻次数)/传球次数*100% 。这项数据清楚显示球员帮助队友得分的积极度。 http://tinyurl.com/otmnsgj (图四) In this graph, the solid line is the league average and the dotted line are 1*SD from the league average. Players who has highest assist opportunity% numbers were playmakers who are good at creating for their teammates. Players clustered with highest AST Opp% are: (roughly by order: Kobe Bryant, Ty Lawson, James Harden, Chris Paul, Reggie Jackson, Jameer Nelson, Russell Westbrook, Rajon Rondo, Ricky Rubio, John Wall, LeBron James, Stephen Curry etc.) 上图中，实线为联盟平均，虚线则距平均值有1个标准差。 高助攻机会%者即为所谓的playmaker，擅长为队友制造机会。高助攻机会者依序大致为 Kobe、泰劳、哈登、CP3、Reggie Jackson、Jameer Nelson、Russell Westbrook、 Rajon Rondo、Ricky Rubio、John Wall、LeBron James、Stephen Curry。 Lin stands out here with way above league average assist opportunity percentages within this team. Pretty much 1 out of 4 passes is for his teammates to score. Batum was a bit lower than I anticipated but still above league average. And Kemba Walker is less active in looking for opportunities to set up his teammates. He would be below average in PG category, only 18% of his passes were trying to set his teammates up. 上图Lin平均助攻机会%可谓名列前茅。传出去的4球中有1球就是为了队友投篮。Batum比 我想得低一点，但仍为高於联盟平均。坎巴在为队友寻求机会上不是很积极。在PG之间低 於平均，仅有18%是为了帮队友制造机会。 Last, I look for their assist success rate, which I calculated using following formula: (AST+FT assist)/assist opportunities*100% This is an indication on how good a player is in generate looks for their teammates, and a good play maker would have better success rate, and a not so good play maker would have lower success rate. (Unfortunately, finishing capability of teammates could affect this number a lot too, thus that might need to take into consideration when player were compared across different teams.) 最後，我用下面公式计算他们的助攻成功率：(助攻+ FT assist 罚球助攻?/助攻机会 *100% 这数据能表示球员为队友制造机会的积极度，通常一位好的playmaker的成功率也较高， 反之亦然。 但当然队友的finish能力会大幅影响这项数据，所以比较各队之间时必须考量此点。 http://tinyurl.com/pd2daek (图五) Again, the solid line indicate the league average, and dotted line indicated 1SD from league average. Batum is really good in terms of assist success rate, and Lin is above average too. Kemba Walker was below average there. 同样地图中实线为联盟平均，虚线则距平均值有1个标准差。 Batum助攻成功率极出色，Lin也是水准之上。坎巴则低於平均。 So, looks like Walker, Batum and Lin are all willing passers, with Batum and Lin being better play makers on this team. Lin is more active in looking for opportunities to set up his teammates, and Batum somehow generate better looks to have better success rate. Other guards are not much play makers on this team unfortunately. 结论上来说，目前黄蜂队内坎巴、Batum和Lin传球意愿高。Lin是出色的playmaker，且积 极为队友制造机会，Batum则助攻成功率高。不幸的是其他蜂蜂後卫都不算playmaker。 Looking forward to see Walker/Batum, Walker/Lin Batum/Lin pairing in game situation, and I would really like to see all three of them on court together, could be a really dynamic line up with three ball handlers, two play makers on the floor, would be fun to watch. 我很期待看到日後比赛中Walker/Batum、Walker/Lin和Batum/Lin等搭配， 甚至期待三位同时上场的情形，因为有两位playmaker在场，想必会打得活力四射、 趣味横生~ --
