THE FIRST TIME RYAN RICHARDSON was suspended from coaching volleyball, in early 2024, he gathered the parents of his teenage players in the back room of his gym in the border city of Pharr, Texas. It was a dark, cool space, one wall lined with shelves of trophies and dangling medals. The tinted windows looked out onto the courts where Richardson trained some of the best young female players in the Rio Grande Valley, but the glass was one-way, and from outside, nothing that happened in the room was visible.
