This study examined offensive tactical patterns in professional basketball and their relationships with scoring performance under varying contextual factors. Data from 982 games in the 2023-2024 Chinese Basketball Association regular season were analyzed. A k-means clustering procedure identified three offensive archetypes: Individual Creation Style (ICS), Pick-and-Roll Variation Style (PNRS), and Screen-Post Synergy Style (SPSS); random forest classifiers with Shapley Additive exPlanations confirmed cluster separations. Correlation analyses showed that isolations and pick-and-roll (PnR) handler plays in ICS were moderately associated with two-point shots made (r = 0.31) and accuracy (r = 0.30); hand-off actions in PNRS weakly correlated with two-point shot accuracy (r = 0.12); and off-ball screens in SPSS were moderately related to three-point shots made (r = 0.31). Poisson regression models revealed contextual effects. Specifically, PnR handler plays increased against stronger opponents (p < 0.001), isolations occurred more frequently in faster-paced games (p = 0.002); hand-off completions were greater in wins (p = 0.034) and against stronger than weaker opponents (p = 0.034); and off-ball screens increased against medium-level opponents (p = 0.011) and after longer travel distances (p = 0.033). These findings provide a scalable analytical framework connecting tactical structures, scoring outcomes, and situational constraints in professional basketball.
