I would imagine the only livestream will happen through the Nfhs/ KHSAA
They usually stream all the state championship games

I believe PrepSpin offers a package. I've always used my NFHS account, but word is it is a much better broadcast. To my understanding they feed it to you directly with the purchase. NFHS receives the feed from them and compresses it which decreases the quality and increases lag. I find it's not worth paying an extra $70 since I already subscribe yearly to NFHS. Plus, the dickhead overlord that runs the other sight always promotes them. 

I usually watch them on demand which eliminates the lag. The quality has never been an issue to me, just the inconsistent lagging. Since you're a fan of one of the teams you might consider paying for the 4A game. It's usually around $15
