Most of these players are in fact not in high school, so your lineup is wrong.
These players went to the NBA straight out of high school, so the name doesn't imply that they're in high school. It signals that they performed well enough during high school that they weren't required to show their skills at the college level.
Ngl this team besides the starting team is kinda weak.
Not many players have come from high school, and the constant rule changes have prevented several players being drafted who were ready for the NBA as high schoolers.
