Early on in high school he was a shooter, by the time he was being recruited and ending high school, he was much more of an all around player.
His senior year he shot less than 40% from the 3 point line, and less than 80% from the free throw line. He also wasn't a high volume scorer, either in AAU or in HS. He only averaged around 18-19 ppg game. Yet he won Mr Basketball because he was a very good all around player, on a very good team. He was also a leader and good all around player on his AAU team.
Your buddy coached his Indiana Elite team? Or one of his earlier AAU teams?
There are countless articles that talk about him changing his game from being just a shooter, to being an all around player, during high school, and that being why he won Mr Basketball, and ended up at IU.
