Although there has been an increase in research aimed at promoting and managing the mental health of student-athletes, the mental well-being of coaches remains underexplored. Research indicates that the mental health profiles of coaches are similar to those of elite athletes [1] and should receive comparable attention. The introduction of Name, Image, and Likeness (NIL) legislation, along with the rise of the Transfer Portal in collegiate athletics, has presented student-athletes with new and unexpected options, which also bring novel challenges to coaches and potentially impact elite-level coaches’ mental health. This manuscript will identify three categories of stressors—performance, organizational, and self-related—that affect elite men’s college basketball coaches, highlighting how NIL and the Transfer Portal exacerbate those stressors and their impact on coaches’ mental health.展开更多
