I don't think you understood the complaint being made in the post you quoted.
Hint: they want a B12 network NOT to watch football or mbb, but women's sports which they don't believe ESPN+ will bother to broadcast.
I don't believe you, or anyone else can say with any certainty what the future coverage of, say B12 women's volleyball is going to look like.
I understand what was being said and it's apparent that you might not have been an ESPN+ subscriber because there are a lot of women's sports on that including volleyball, soccer, and wlax for CU.
That's why there's no need for a B12 network at this point.
