In case you hadn't heard, all NCAA games are on Joost
There’s a fair amount of warning that this is a test of Joost’s live streaming capabilities, so take that into consideration if you’re hell bent on being able to watch the games reliably. There’s also CBSSports.com’s live stream as well, so you’ve got a couple great options.
Oh NFL, why can’t you be more like the NCAA?
