Abstract
During the period of 2006–2008 Major League Soccer made a series of rule changes regarding roster structures and how clubs obtained players. These changes include: creating Designated Player roster spots, increasing the number of international roster spots, and allowing clubs to sign players from their academies. This work examines the impact of those rule changes on the MLS careers of players selected in the MLS SuperDraft. Statistical methods to compare two groups and regression models are used to examine possible impacts. There is a significant decrease in the probability of players selected after the rule changes going on to play competitive games in MLS. These results may impact how clubs choose to allocate resources for player recruitment.
在2006年至2008年期间，美国职业足球大联盟（Major League Soccer）对球员名册结构和俱乐部获得球员的方式进行了一系列规则更改。这些变化包括：创建指定球员名单名额，增加国际球员名单名额的数量，并允许俱乐部从他们的学院签下球员。这项工作考察了这些规则的变化对美国职业足球大联盟超级选秀球员职业生涯的影响。使用统计方法比较两组，并使用回归模型来检查可能的影响。规则改变后，被选中参加美国职业足球大联盟竞技比赛的球员的概率显著降低。这些结果可能会影响俱乐部如何选择为球员招募分配资源。
