mj had a growth spurt his jr year of hs (the rest of his family is < 6') scottie had a giant growth spurt in college (was a walk on point guard and was 6') kelly olynyk is a local example of a guy who grew late in hs (also a pg before growing). bill walton was normal tall, his brothers are 6'3"ish (nba pg height), but then shot up 8 inches to 6'10" his jr year of hs. many many examples. Robinson for sure the most drastic bc he grew in the navy
now that you mention it, you have a good point that it seems less common lately
