If Duke were to ever consider doing something like this, I would hope the contract would ensure that the cable/satellite providers carry the channel.
I live in Central Florida and would guess this "honeymoon" will be short-lived as Brighthouse in Central Florida and Fox have an ongoing battle now well into its second year. No ACC Sunday night basketball games nor half of the Magic games are available.
The best news about all this is with the huge alumni base in Central Florida from UF, there certainly will be pressure to resolve the issue one way or another.
