Analyzing shooting performance
I'm considering various factors that might affect shooting quality, like player position, defensive schemes, and key players being absent. It makes sense to suggest adjustments like changing lineups, increasing rim pressure, and running specific plays. Notably, a poor shooting percentage, like 2 for 22 at halftime, may regress toward expected averages in the second half. I plan to compute probabilities related to expected makes in this scenario to illustrate its rarity. Additionally, shot profile adjustments could lead to better results.Proposing second half KPIs
I think we can suggest key performance indicators for the second half, like focusing on easy scores at the rim or free throws to build confidence. Pacing the game will help too, along with specific set plays for star players. Even though the user didn’t specify the team, referencing "勇士" keeps it clear. I’ll structure the response in simple bullet points without heavy formatting and add a follow-up question: "要不要我把这场比赛的下半场关键回合做个复盘？"
看点与解读：
- 2/22 半场三分是极端冷手感（≈9%）；若球队正常三分命中率在 35%–38%，按二项分布估算这种半场低迷发生概率不到 1%，从概率上确实“会回归正常”。
- 先分清“投不进”还是“投得难”：若多为急停/运投、干扰重、时间耗尽的出手，命中率低可预期；若是大量空位却铁，更多是方差与手感。
- 对手策略可能在诱导：收缩内线、放投非核心射手、延误手递手与掩护追防，把无球战术拆解，导致出手质量下降。
- 体能与赛程会放大方差：背靠背、轮换短、核心受压迫时，腿部疲劳先体现在三分。
- 心理链式反应：连续打铁后犹豫、出手节奏变形；需要通过“看到球进框”打断。
下半场可做的即时调整：
- 先拿“保底分”：多打挡拆攻击篮下与造犯规，借上罚球与上篮找手感。
- 提升出手质量：多用弱侧空切、短传顺下（short roll）和二次转移，让外线更多接球即投而非高难运投。
- 定制战术包：为核心射手跑一两次指向性战术（电梯门、Spain PnR 侧翼溜底线），迅速“开张”。
- 改变阵容节奏：上更能推进和冲板的组合，提高转换进攻比重，趁对手未落位出手。
- 细节：多争前场板制造二次进攻三分；避免早期仓促三分，优先深度触及禁区后再外传。
赛后复盘关注点：
- Shot quality：C&S vs 运投比例、空位/大空位命中率、45°与弧顶/底角分布。
- 战术完整度：无球掩护质量、手递手被延误后的应对（短切/背掩护是否跟上）。
- 人员使用：对方针对性换防或夹击后，非持球点的惩罚是否到位。
需要的话，我可以按“出手质量”和“战术执行”两个维度，给你列一份复盘清单，或者做个简短模型估算这类半场低迷后半场命中率回归的区间。
