From: "David Montgomery" Thought I'd pass it along, there's an upcoming documentary from the director of "Hoop Dreams" (considered to be one of the best documentaries ever, if not THE best) called "Head Games", which chronicles Chris Nowinski's quest to bring to light the issues of concussions in sports, esp. for young athletes. The first trailer was just released: http://www.youtube.com/watch?v=1r_e4dkyBgo
