There are compelling arguments for a "ground-up" collaborative approach to FCS Conferences banding together to negotiate better TV rights for all the schools of their subdivision. But to Disney, it's like pennies to them, so FCS is not valued properly as an asset overall.
I know this isn't a popular perspective on an FCS board -- and understandably so -- but Disney's view on this is the prevailing one. College sports is, first and foremost, a business and that business revolves nearly entirely around FBS football and men's basketball. FCS football is, from a business perspective, a niche market and just doesn't move the needle in large scale corporate decisions. FCS conferences banding together to negotiate with Disney would have the same appreciable negotiating power as any one of them already has.
