MHSAA TV
For those of you who haven't heard, the Michigan High School Athletic Association has made a deal with Comcast to show games on their cable system. Not only do they show it on tv, but they have a website that streams old games. Unfortunately, I don't think they have any live broadcasts, but they do have an archive of old games that you can stream from their website. They show all sports; football, volleyball, basketball, and many others. They don't have video in every section as of yet, but it appears they will have video from every sport the MHSAA sponsors.
