People think ESPN pays decent money to broadcast high school games. They do not. Last year two teams in Alabama were paid $1,000 each.
Its all about timing. If the NCAA leaves Friday nights alone then I think a national HS matchup or something regional done by a local cable affiliate might make sense. I also think that in season football in general is now suffering from some over saturation. Too many games, too many nights of the week. Dead of the summer like now they will try anything to draw eyes. Hell Fox sports south is broadcasting the semi's and finals of this weekends Powerade 7 on 7 . Talk about desperate for content.
