You guys should check out the biography on the perfect Thornridge team of '71-'72. It's called "Thornridge: The Perfect Season in Black and White". It was released in November 2009. The author was a player at Lincoln HS at the time so he has an interesting perspective.
One of the best sports books I've ever read. Great story that spoke as much about social issues of the time since Thornridge was a recently desegregated school in the late 60's. Excellent story that would make a very good movie.
I highly recommend it.
