From the perspective of career development, this research explores the transition process from the role of basketball player to coach. It uses semi-structured in-depth interviews to interview eight basketball coaches who have experience in division-one players, and uses the environment, system and initiative as the framework. The results of the study show that there’s seldom chance to explore other fields due to the long training time during the player stage. When switching to a coaching role, you may face difficulties in training, interpersonal interaction, family factors, and salary condition. The strategy of coping with the difficulties is through continuous learning, self-reflection, humility and never giving up. Counseling is one of the important tasks of the coach's role. The degraders use the experience of the past to train student basketball players to learn positive value, analyze their own value, respond to changes in the environment, and other abilities to create their multiple career paths.
