In the past it was live streamed by the NFHS (National Federation of High Schools) because they owned the rights to the broadcast. Unless and until that changes, that is where you have to go to watch. I believe it is part of larger package of state championship broadcasts negotiated by the AHSAA.
He is correct. The NFHS Network bought the rights -- but their idea of streaming the state meet is to show finals on Saturday.... too bad for all those "non final" events on Friday (you can read that sarcasm in that).
We tried negotiating for rights and was told the NFHS had all of the rights retained.
