I just don't think it makes a difference.
I'm a pretty big OU basketball fan. I don't have much interest in watching us play a mid-day game, against HS-level competition, on what was likely to be a terrible feed/stream.
Would I have? I probably would have tried to watch some of it, sure. But those that have jobs that don't let them be glued to their phone/computer during the day? Those that are more casual fans? And again, what's the loss for OU? OU isn't LOSING fans by not streaming these games. All of ya'll that are mad, you are still going to watch the games next year. Go to the same number of games you'd have gone to before. And all of that jazz.
So I'll say it again, there really isn't much incentive for OU to find a way to broadcast these games.
