Since 2006, the so-called one and done rule prevents American high school players from joining the National Basketball Association (NBA) without at least 1 year of college basketball experience. While there is debate about the pros and cons of the one and done rule, few studies have fully examined how minimal (or no) college experience relates to performance in the NBA. The current study used publicly available offensive and defensive statistics for all players in the NBA from 1995 to 2016, to examine the relationship between years of college experience and career success in the NBA. Results showed that players with less college experience had better offensive, defensive, and advanced metric (player efficiency rating [PER] and value over replacement player [VORP]) statistics than players with more college experience. However, players with less college experience also made more mistakes in game play, such as turnovers and fouls. The results suggest that college players may not need to attend college to succeed in the NBA.

一劳永逸：检查国家篮球协会的大学篮球经历年限与职业统计之间的关系

自2006年以来，所谓的“一劳永逸”规则阻止了没有至少一年大学篮球经验的美国高中球员加入美国国家篮球协会（NBA）。尽管关于“一劳永逸”规则的利弊争论不休，但很少有研究充分研究过最少（或没有）大学经验与NBA表现之间的关系。当前的研究使用了1995年至2016年NBA所有球员的公开进攻和防守统计数据，以研究NBA多年大学经历与职业成就之间的关系。结果表明，大学经验较少的球员的进攻，防御和先进指标（球员效率等级[PER]和替换球员的价值[VORP]）要比具有更多大学经验的球员更好。然而，大学经验较少的玩家在游戏中也会犯更多的错误，例如失误和犯规。结果表明，大学球员可能不需要上大学就可以在NBA取得成功。
