在當今社群媒體和數位行銷迅速發展的背景下，個人品牌的建立已成為許多運動員重視的核心議題。本研究首先探討NBA選秀的規則與其演變，並基於大學運動數據與體能測試數據，使用因素分析中的主成分方法將29項變量分解成七大構面。透過多項式邏輯斯回歸模型，樣本為260位參與NBA選秀大會的球員，使用College Basketball section of Sports-Reference的資料、National Basketball Association（美國職業聯盟）的官方網站、Basketball Reference 資料庫 。詳細分析了這些構面對選秀輪次的影響。得出在投籃效率和進攻貢獻因子在所探討的三個模型中均顯著正相關於選秀輪次，表明投籃與進攻的綜合指標在選秀裡扮演重要角色。然而，本研究卻發現，比賽場數較多的球員在模型中大部分皆呈現顯著負相關，反而會造成選秀中的輪次更低。

In the context of rapidly evolving social media and digital marketing, the establishment of a personal brand has become a core issue for many athletes. This study first explores the rules and evolution of the NBA Draft, and uses principal component analysis within factor analysis to decompose 29 variables into seven major dimensions. A polynomial logistic regression model was applied, analyzing a sample of 260 athletes participating in the NBA Draft, using data from College Basketball section of Sports-Reference, the official NBA（National Basketball Association）website, and the Basketball Reference database. The analysis detailed the impact of these dimensions on draft rounds. It was found that shooting efficiency and offensive contribution factors were significantly positively correlated with draft rounds in all three models examined, indicating that these composite indicators of shooting and offense play a crucial role in the draft. However, the study also unexpectedly found that players with a higher number of games mostly showed a significant negative correlation, leading to lower draft positions.
