Hey Iowamom,
I'm part old school traditionalist so, for game coverage, I still like to see box scores and highlight summary. While HS stats are available online, I think we are generally still at the point where mom and dad may subscribe but not many others. So, there is still value in posting the information in the local paper (whether print, online or both) where friends and other family will see. Occasional game action pics are great and a key compelling draw . Include in the summary any relevant league standing and overall record information, how the game may have impacted league race, etc. Any quotes/interviews from players and coaches add personal interest and unique perspective.
As far as play-by-play, a local TV station had a feed that would provide some of that, along with scoring updates, for Friday Night Football around the area and I was drawn in to follow that. I just don't associate that with the local newspaper and it seems that would require more extensive efforts with networking resources, but I could be wrong.
Outside of specific game coverage, other things I like to see... weekly league standings/overall records, personal interest stories, pre-season team-by-team outlook, coverage of all-league, all-county (maybe even sponsorship of), etc., player college commitment updates, extra playoff coverage, etc.
Up until maybe four or five years ago, the local papers and TV stations did a pretty good job. If I were to steal the best methods from various outlets and combine them for best coverage, these are the things that seemed to work best...
Try to make it out to games for each local team here and there, offering your own highlights, game summary, interviews, game pics/video, etc. Of course you can't make it to every game. But your presence at some games for each local team will cultivate better collaboration with the coaches/programs for gathering info remotely. They'll know you are fully engaged and supportive. Identify key contacts that can send you info in your absence. As a HC, I used to get calls from the local media the same evening of games, usually while I was driving home from away games or finishing field prep at home games. They would ask me to either read off to them the highlights and what players stood out (similar info as RJM describes) or have me send them an email or text with the info. I would always have a few parents or friends of the program that loved taking pics send me the best of what they had for a given game and I would forward that with description of play/action along with my game recaps to the media. That way, the media could cover most every game without having some one attend each. I'm sure I'm not telling you anything new there.
As things started to deteriorate with coverage in our area, the local media started getting lazy and basically telling us if we wanted coverage, submit our own info by X time. That would have been OK if they would have been consistent with using the information. But when they started only posting once in a great while, there was no incentive to continue posting.
In some areas, schools are either required or are pretty consistent with posting on MaxPreps. I suppose info can be taken from there with the right approvals.
