what's the "Freaks and Geeks" / "Orange County" connection?

After watching “Freaks and Geeks” recently on DVD, I started wondering what happened to the teen actors in the series, most of which did oustanding, should-have-been career-making jobs. So I went over to IMDB, and most of them haven’t done much - except a large number - at least six or seven - were in the movie “Orange County.”

Does anyone know why? The show and the movie don’t seem to share a producer or director or writer or anything that would be expected to port them over.

Mike White wrote Orange County and some episodes of F&G if that helps.
