My buddy's son plays youth football down on the peninsula for the Bayside Broncos. He said the Serra HC Pat Walsh has a son the team. Walsh has the Serra O/C drawing up the plays and coaching the bayside broncos offense on the weekends. Now this is a great way to recruit kids into a program.
My buddy also said that his kid goes to Serra practices and hangs out on the field with the coaches during practice.
If a public school was doing this on the peninsula this would be considered illegal recruiting. Youth football and youth camps are a great way to get to know the kids and parents. Public schools need to figure it out or be left behind.
