斯蒂芬·卡斯尔 (Stephon Castle) 正在打出一个现象级的赛季。在荣膺年度最佳新秀后，他在比赛的各个方面都取得了进步。场均 16.5 分、5.1 个篮板和 7.1 次助攻的数据听起来很棒，但对于像卡斯尔这样的球员来说，这远不能概括他的全部贡献。
目前，他的投篮表现并不算突出，51.1% 的有效投篮命中率低于联盟平均水平。虽然这不算出色，但他依然是场上最高效的球员之一。他带来了许多无法体现在数据统计表上的无形特质，但这些特质在球队的胜场数中发挥了实实在在的作用。
深入探究一下，是否有办法量化卡斯尔每晚带来的更多贡献？答案是肯定的。高阶数据开始以更直观的方式揭示马刺队和卡斯尔成功的秘诀。
正负值数据是首选的切入点。他在场与不在场时，球队的表现有何不同？总的来说，这并不是一个完美的指标，因为数据中包含很多干扰因素和离群值（例如与谁同场竞技），在单场比赛中可能会产生误导，但在观察大样本量时，这是一个不错的起点。卡斯尔的原始正负值为 +5.5，表现相当不错。
其次是他的防守。卡斯尔是目前联盟中最顶尖的领防者之一，对任何 NBA 持球人来说，他都是一个真正的麻烦。根据 cleaningtheglass.com 的数据，当卡斯尔在场时，对手每百回合得分会下降 4.7 分。虽然这不能完全归功于卡斯尔，但这一数据非常显著。如果卡斯尔最终没有入选最佳防守阵容，那才令人意外。
接下来是进攻，首先是转换进攻，马刺队本赛季在这方面非常高效。根据 Cleaning the Glass 的数据，他们在防守篮板后的每百回合得分排名联盟第一（+1.9），整体每百回合得分排名第六（+3.4）。卡斯尔的作用体现在当他在场时，球队能够更频繁地进入转换进攻。当卡斯尔在场时，球队的转换频率整体提升了 2.3%（超过联盟 93% 的球员），而在抢到防守篮板后的转换频率则提升了 6.3%（超过联盟 97% 的球员）。简而言之，只要卡斯尔在场，球队抢到篮板后就会立即发动快攻。
那么冲击篮筐的表现如何呢？他的投篮手感或许还没找回来，但他能杀入篮下。他有 43% 的出手是在篮下完成的（在双能卫中排名第 93 百分位）。不仅如此，卡斯尔在投篮时被侵犯的比例高达 20.5%。虽然他的投篮命中率不算高，但如果每五次出手就有一次能让他走上罚球线（他的罚球命中率为 74%），这就足以弥补投篮的不足。
看看更复杂的综合指标，即那些试图剔除干扰因素以衡量球员实际贡献的数据，比如 Dunksandthrees.com 的预估正负值 (Estimated Plus-Minus)。他的这一数值为 +2.8。作为参考，这处于全联盟第 93 百分位。总的来说，对于一名年仅 21 岁且仍有巨大提升空间的球员来说，这是一个非常了不起的数据。
综上所述，卡斯尔是一名能带来胜利的球员。他并不追求个人数据，而是总能找到影响比赛的方法，无论这种影响以何种形式呈现。现在，随着这支年轻的球队首次进入季后赛，我们将拭目以待卡斯尔能否保持这种状态，甚至更上一层楼。

Stephon Castle’s impact goes well beyond the stat sheet
Stephon Castle is having himself a season. He has followed up his Rookie of the Year with improvements to every aspect of this game. Averaging 16.5 points, 5.1 rebounds, and 7.1 assists sounds great, but for a player like Castle, it just doesn’t tell the whole story.
Currently, he doesn’t shoot particularly well, averaging a below-average 51.1 percent effective field goal percentage. That isn’t great, but he’s still one of the most effective players on the court. He brings a number of intangible qualities that don’t quite make it in the box score but do make their effect felt in the win column.
Diving a little deeper, is there a way to quantify more of what Castle brings night after night? Yes. The advanced stats start to shed more light on the Spurs and Castle’s success in a more tangible way.
Plus/minus stats are the first place to look. How does the team do with him on the court versus off? Overall, it’s not a great metric because the data carries so much noise and outliers (such as who he shares the court with) and can be misleading in any particular game, but it’s not a bad place to start when looking at a large sample size. Castle’s raw plus/minus is +5.5. Not bad at all.
Second is his defense. Castle is one of the best point-of-attack defenders out there and a genuine pest to any ball handler in the NBA. Looking at opponent points per 100 possessions, it drops 4.7 points with Castle on the floor, per cleaningtheglass.com. That isn’t all attributable to Castle, but it is notable. It would be surprising if Castle isn’t on an All-Defense team.
Next up is offense, beginning with transition, where the Spurs have been very efficient this season. Per Cleaning the Glass, they are first in points per 100 possessions off live rebounds (+1.9) and 6th in overall points per 100 (+3.4). Where Castle comes in is how often the team is able to get into transition play when on the floor. That transition frequency goes up 2.3 percent (93rd percentile) overall, and 6.3 percent off of live rebounds (97th percentile) with Castle in the game. In short, the team gets rebounds and goes with Castle on the floor.
What about getting to the rim? His shooting may not be there yet, but he gets to the basket. 43 percent of his shots are at the rim (93rd percentile among combo guards). Not only this, Castle is getting fouled on a whopping 20.5 percent of his shots. He isn’t shooting particularly well, but if one out of every five of those shots gets him to the free-throw line, where he shoots 74 percent, he’s making up for it.
Looking at a more sophisticated all-in-one metric, one that tries to pare down the noise to a player’s actual contributions, there is Estimated Plus-Minus from Dunksandthrees.com. He’s at +2.8. For context, that’s 93rd percentile league-wide. Overall, a pretty remarkable figure for a player who is only 21 years old and only going to get better.
All of this is to say that Castle is a winning player. He isn’t out for his own stats and finds ways to impact the game, no matter what that looks like. Now, as this young team enters its first postseason, we’ll see if Castle can keep it up, if not find another gear.
