Boston Celtics Coach Ime Udoka, New Orleans Pelicans Coach Willie Green and Jerry Stackhouse, who coaches the Vanderbilt University men’s basketball team, have attended the camp. This year’s coaching group included one player from the W.N.B.A.:Marie Ferdinand-Harris, a retired three-time All-Star. The N.B.A. players ranged from those who had brief careers, like Peyton Siva, who appeared in 24 games for the Orlando Magic in 2013-14, to the more established, such as Rodney Hood, who has been in the N.B.A. since 2014.
