NCAA Live Video feeds
Not that I would EVER do this, but if you check out http://www.ncaasports.com/, all games are available to watch for free via streaming video. i signed up as a VIP, and its pretty great...
Tech wise, the video looks really good for a free service, and the audio is fine. you can even hear the announcers setting up and discussing things before the game...they also have a hilarious "boss button" that loads up a dummy Excel spreadsheet. :-)
now get back to work, minions.
