A kid from a former soccer team my daughter played on got a D1 scholarship to a top school this year. Last I saw her when she was 13, she was the worst on the team, unathletic too, could not run properly. Her development is not a matter of LATE growth or growing into a more adult body. She comes from a very rich family. Father has a jet. Well, she got all the training in the world, trains on her skills for many hours every day, and has translated that to a hustle mentality on the field. Good for her, works very hard. Now she gets rewarded. This is a mix of very hard work by the kid and money that won her that scholarship.
