Brentwood recruited so hard in the early 90's (for football) the public schools finally convinced the TSSAA to have two state champions. One for the public schools and one for the private schools.
Oh, and when I went to ECS in Memphis it cost 5,500 per year. It cost 12,500 now. Private schools in Memphis (and probably all of Tennessee) have estenially entered an arms race to stay competitive with each other. MUS is 15,500 last time I checked.
