I just paid for BTN Digital... I think it was $14.95 for one month. I thought I was supposed to be able to buy Nebraska Only for $9.95, but that option never came up.
I am more concerned with whether they will play it at all, or what their plans are if the weather gets real ugly. I streamed the Indiana Spring game to test it, and after the first quarter they stopped it an moved it to an indoor practice facility.
