You're most likely aware of the Ed O'Bannon suit and what it might mean for the NCAA. But you may not be aware (we weren't) that a class action lawsuit about concussions and head injuries may also be brewing. The O'Bannon case could upset the economic model the NCAA uses; a suit of this kind would directly target football and could force massive changes which might make the game far less appealing.
Keep an eye on this one.
