Your points are flawed in the fact that you keep comparing a public school to a private school. There is no comparison. You keep bringing up players who opted to attend a better public HS, within the rules, yet try to explain away the same situation for a private school. It's a good thing we live in America, where we can make our own choices, within applicable rules and laws.
I could care less what is fair and what is not. As long as you are following the rules, it is fine in my book. If DLS chose to waive tuition or give a scholarship for a kid from Oak Park, that was in the Sac High school district, then so be it. Good for him. But don't chastise others who made similar decisions, just because you are trying to troll.
I think the Ngata brothers parents decision worked out well. Clemson and Notre Dame aren't bad schools, considering they paid nothing for HS to garner those rides. Me likes!
