When David Robinson was a junior in high school, he was something like 5'9" tall. By his senior year of high school, he was 6'7". He was also rail thin in high school. I don't remember the weight, but he was definitely under 200 lbs when he graduated. Then, of course, he just kept growing and became too tall for the Navy. lol. So, if Dabone really is that age, I predict he'll be over 8 feet tall. lol.
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. .... Robinson is widely considered to be the best basketball player in Naval Academy history. He chose the jersey number 50 after his idol Ralph Sampson. He began college with no expectations of playing in the NBA, but in Robinson's final two years he was a consensus All-American and won college basketball's two most prestigious player awards, the Naismith and Wooden Awards, as a Naval Academy first classman (senior). In 1986, Robinson led Navy, a number seven seed, within a game of the Final Four before falling to Duke in the East Regional Final. from wiki https://www.sports-reference.com/cbb/boxscores/1986-03-23-duke.html
