Experience is an important asset in almost any professional activity. In basketball, there is believed to be a positive association between coaching experience and effective use of team timeouts. Here, we analyze both the extent to which a team's change in scoring margin per possession after timeouts deviate from the team's average scoring margin per possession-what we called timeout factor, and the extent to which this performance measure is associated with coaching experience across all teams in the National Basketball Association over the 2009-2012 seasons. We find that timeout factor plays a minor role in the scoring dynamics of basketball. Surprisingly, we find that timeout factor is negatively associated with coaching experience. Our findings support empirical studies showing that, under certain conditions, mentors early in their careers can have a stronger positive impact on their teams than later in their careers.
经验在几乎所有的专业活动中都是一项重要的资产。在篮球中，人们普遍认为教练经验与有效利用球队暂停之间存在积极的关联。在这里，我们分析了球队在暂停后每回合得分的变化幅度与球队每回合平均得分的偏离程度——我们称之为暂停因子，以及在 2009-2012 赛季的美国职业篮球联赛（NBA）中，所有球队的这一表现指标与教练经验的关联程度。我们发现暂停因子在篮球的得分动态中作用较小。令人惊讶的是，我们发现暂停因子与教练经验呈负相关。我们的研究结果支持了实证研究，即在某些情况下，职业早期的导师对他们的团队的积极影响可能比职业后期更大。
