The public university he is strongly considering does not have club ball. He was accepted at another public, which does have a good club team, but he has dropped that school off his list completely. He applied late at the last deadline at a third public but it will be a few weeks before he hears back from that school. The late application school does have club ball.
I seriously doubt that walking on is a realistic option at the public D1 he has the greatest interest in.
