General Discussion

junior year of high school (age 16–17). However, during his senior year (age 17–18) in high school, he experienced a large growth spurt and grew to 6 ft 6 in (1.98 m). He had not played organized basketball or attended any basketball camps, but the school's basketball coach added him to the team. Robinson earned all-area and all-district honors but generated little interest among college basketball coaches.

Robinson graduated from Osbourn Park in 1983. He achieved a score of 1320 on the SAT and subsequently attended the United States Naval Academy, where he would major in mathematics and play on the basketball team. At the time the Naval Academy had a height restriction of 6 ft 6 in (1.98 m) for all midshipmen, but in the autumn when the new academic year began, Robinson had grown to 6 ft 7 in (2.01 m). Assuming that he was unlikely to grow much more, the academy's superintendent granted him a waiver, but Robinson continued growing, and by the start of his second year at the academy he had nearly reached his adult height of 7 ft 1 in (2.16 m), which later prevented him from serving on any U.S. Navy ships.
