현대 프로농구 선수 포지션 역할에 대한 새로운 접근 : 주성분 분석을 통한 NBA(미국프로농구) 선수 포지션 재정의 = A New Approach to Modern Professional Basketball Player Positions: Redefining National Basketball Association (NBA) Player Positions through Principal Component Analysis

다국어 초록 (Multilingual Abstract)

Purpose: This study aims to empirically reclassify the roles of National Basketball Association (NBA) players, moving beyond the traditional categories of point guard (PG), shooting guard (SG), small forward (SF), power forward (PF), and center (C).
Method: We utilized the game statistics from three NBA seasons (2020-2023) to redefine players’ positional roles. We employed principal component analysis and regression analysis, utilizing Python and SPSS 26.0 software package for methodological assessment.
Results: The empirical results of the principal component analysis showed that modern NBA players can be categorized into six distinct roles: Big Man, First Option, 3-and-Defense, Defensive Guard, Bench Ace, and Role Players. Regression analysis identified 155 players as Role Players, 145 as Big Man, 126 as First Options, 87 as 3-and-Defense players, and 75 as Defensive Guards.
Conclusion: This study holds academic and practical importance by systematically collecting, preprocessing, and analyzing extensive NBA data. It redefines player roles based on modern basketball play styles and provides a comprehensive list of players corresponding to these new categories, offering a fresh perspective on player posions.
