You're correct Dosso.
Coach Robinson is still involved with the Stealers program in the sense that he started it and runs the open clinics during the summer, but he does not actually coach the kids at any level of the program due to his involvement with USA Basketball. His role is more administrative these days. The game/tournament coaches are from all over the area (Bishop assistants included).
Bishop was hit hard by the downturn in the economy and you're just now starting to see the effects. Most of the families at Bishop are middle class, so when the economy went down, they opted to send their kids to their local public schools. As a result, the enrollment has been way down recently, which means less athletes.
With things bouncing back, the enrollment should start to rise again and you'll see more athletes for the major sports. You'll start to see it next year for the girls hoops team. They've got a couple of really strong players coming up from the feeders that will contribute immediately. They won't contend next year, but they won't take much of a step back either.
