to add to these good points, I would add my observations:
Often spectators will be screaming/yeelling while the same team's coaching staff is not saying one word. Hmmmm, if the coaches are not upset, why would the spectators?
Also regarding the rules, the local cable network does a 'game of the week' like many other cities. They do a good job too.
EXCEPT the announcers know nothing about HS rules which obviously makes the officials look bad - because announcers know everything, right?
