Yes, yahoo is charging money this year.
Try this for most teams though. Worked well with a bunch so far and all of last year. Do a search for the school....i.e., university of illinois or such. Find the official website for that school. Go to that page and look for athletics. Find the football page and most of the schools have links to live broadcast that are not yahoo fed. Most of the times its awful announcers, but who cares???
