Johnson spent 16 years in the National Basketball Association as a player, and subsequently served as the head coach of two NBA teams: the Dallas Mavericks and New Jersey/Brooklyn Nets. He led the Mavericks to their first NBA Finals appearance and to three consecutive 50+ win seasons. During his playing days, Johnson was known as the "Little General" for his small stature (by NBA standards), his leadership skills as a point guard, and his close friendship with former San Antonio Spurs teammate David Robinson.
