I track hitting and pitching stats and compile them for every weekend event, tournament/Fall Ball, etc., as well as end of year. I've never made a public offer to share them, and up to this point, nobody has ever asked to see them...other than using them as a guide with assistants to spot trends in either direction, which I find is most useful. This can point out changes in a players production and show patterns of where help is needed on their part. (i.e. suddenly flying out a lot, watching 3rd strikes, looking for walks, etc.) I would make a players stats available to them if they were interested, and would probably go so far as to give them their stats, and let them know whether they finished 4th, 2nd, whatever as far as how they stack up against the rest of the team. But I would not just post everyone's stats available for all to see.
All things considered, stats are just one factor in how you structure your line-up, and there is quite a bit that the stats WON'T tell you. Mental mistakes, consistency of motivation, attitude/effort/chemistry, as well as what can be expected of a player at their particular experience level will not show up in any statistical spreadsheet. If stats told you everything one needed to know about a player, showcasing would be unnecessary. All my players will play as much as possible, so we try to predict our opponents strengths and field accordingly. With this in mind, there are opportunities to move players around, so that we seldom have our entire "A" team on the field. This balances out "winning at all costs" with that of enough playing time for development.
It's long been my opinion that when you put a player into a position of permanence, you risk 3 negative factors:
1.) Complacency from no threat to lose their position.
2.) No opportunity in the eyes of other players that desire to "win a spot"
3.) You limit that players versatility and future opportunities (HS/other travel teams, etc.)
Though I don't really pay that close attention to individual defensive stats, I do look for trends there as to where we're breaking down and allowing runs to score. Sort of a view from 20,000 feet. I usually do this before tryouts to figure out what type of player(s) we are looking for that can strengthen the squad as a whole. It rarely means that we are parting ways with players if we need to strengthen a position or two, it could just mean that there are other positions that returning players could be better suited to within our depth chart.
One other thing to consider is that over the course of the year, we may have 3 or 4 different people keeping the scorebook, so much of the end user data could be up to the interpretation of who happened to be keeping score. Factor in those that use Gamechanger or iScore on their own, and rarely will there be any sort of consensus anyway.
