According to ESPN, NBA club owners are interested in the mental health of their players.
Such statements from the major shareholders of the clubs appeared, when Demar Derzon (San Antonio) and Kevin Love (Cleveland) had publicly announced their health problems, which led to certain problems.
Shareholders, who invest a lot of money in the development of their teams, decided that they need to be aware of absolutely all the subtleties, and asked the basketball players to provide them with the certificates of mental health.
It is worth noting that the Union of players NBA responded to this request of the shareholders very negatively. They think, it violates the personal rights of the players.
