In elite basketball, closely contested games are often decided in the last minute, where a single possession can significantly alter the outcome. The objective of this study was to analyze the offensive patterns and effectiveness of successful play sequences executed during the last minute and overtime periods of the 2022–2023 EuroLeague men’s basketball season. Specifically, we examined how offensive strategies varied based on score conditions and team status (winning, losing, or tied) in games with a score difference of three points or fewer, representing a maximum one-possession margin. The sample consisted of 709 technical–tactical actions performed in one-possession games during the last minute and overtime periods of the men’s EuroLeague 2022–2023 season. An observational methodology was employed using the LINCE PLUS software with a purpose-designed observational instrument. Descriptive analyses and chi-square (χ²) tests were conducted using SPSS 25, and T-Pattern analysis was performed with Theme 6 software. Statistical significance was set at p < 0.05. The results showed that teams leading at the start of the possession executed a higher number of successful actions, primarily through free throws drawn from fouls committed by the opposing team. Additionally, plays involving few or no passes, executed within the first 17 s of possession, and completed by point guards or centers, were associated with higher success rates. While less frequent, fast breaks proved to be more effective than set offenses. Furthermore, the study highlights the role of elite playmakers in late-game situations, as their ability to read defenses and create scoring opportunities plays a crucial role in determining offensive success. The practical implications of this study can assist coaches in optimizing offensive strategies during high-pressure moments in elite men’s basketball by refining late-game decision-making and tactical planning.

Despite the growing popularity of women’s basketball in recent years, scientific literature on the subject remains significantly less extensive compared to its male counterpart. The main objective of this research was to analyze successful offensive actions and patterns during critical moments in the Women’s EuroLeague. The sample consisted of 377 technical–tactical actions corresponding to plays with score differences of three points or less (one-possession games) in the final minute and overtime periods of the Women’s EuroLeague during the 2021/22 and 2022/23 seasons. This study was based on an observational design, utilizing the LINCE PLUS software together with a customized observation tool. Descriptive statistics and chi-square (χ²) tests were carried out using SPSS version 25, while T-Pattern detection was performed through Theme 5 software. A threshold for statistical significance was established at p < 0.05. The findings indicated that home teams achieved a higher percentage of successful plays compared to visiting teams. Most successful patterns occurred during the final phase of possession (8”–0”), regardless of game location or team result. Additionally, layups, plays involving shots after on-ball screen, and actions following personal fouls demonstrated the highest success rates. The practical implications discussed in this research provide valuable insights for coaches to optimize offensive strategies during high-pressure moments in elite women’s basketball.
