<human>: Dennis Wayne Johnson was born the eighth of sixteen children, to a social worker and a bricklayer who lived in Compton, California, a suburb of Los Angeles. Originally a baseball fan and a Little Leaguer, Johnson learned basketball from his father, but seemed to have neither the size nor the talent to compete with his peers: as a teenager at Dominguez High School, Johnson measured just 5'9" and played only "a minute or two each game". After high school, he worked several odd jobs, including a $2.75-per-hour job as a forklift driver, and played with his brothers in summer league games after work. During this period, Johnson grew to a height of 6'3", and developed what some later described as "rocket launcher legs", which enabled him to jump high to grab rebounds against taller opponents.  Jim White, the coach at Los Angeles Harbor College, had watched Johnson play street basketball; feeling that Johnson excelled in defense, White asked him to enroll. Johnson gave up his jobs and developed into a promising young guard, averaging 18.3 points and 12.0 rebounds per game and leading Harbor to a college junior state title. However, the young guard lacked discipline, often clashed with White and was thrown off the team three times in two years.  At the end of his junior college career, two universities offered Johnson scholarships: Azusa Pacific University and Pepperdine University. Johnson chose the latter, and in his only year there, he averaged 15.7 points, 5.8 rebounds and 3.3 assists per game, and developed a reputation for tough defense. After that year, Johnson made himself eligible for the 1976 NBA draft, but was skeptical that any team would take him. NBA teams were wary of drafting a player with character issues, and Johnson was known to be a troublemaker. CANNOTANSWER
