She is 9 games into her first season of collegiate ball, so it's ridiculous to declare her as a bust offensively. Everyone knows a kid who seemed to blossom overnight once they reached a new level of maturity and the light bulb goes off.
It also sometimes happens that only after reaching the collegiate level that it becomes obvious that the player had peaked in high school athletically. They get away from home, start experiencing new exciting things as young adults, and suddenly basketball isn't as important to them as it once seemed to be. It happens. Brooklyn is NOT that kind of player.
My guess is that Miles is only beginning to understand her potential, and will be one of those players who will steadily blossom into a complete player. I said after her first game she was the steal of her class, and I stand by that. The light bulb is flickering!
