I used to coach one of my son's youth travel team in a pretty good organization (although our team wasn't great). Flat chemistry with low energy with zero leadership being shown the prior year so the coaches wanted to come up with some things to get kids to invest.
My first thought was to vote on captains and have and maybe have few of the harder working kids who showed some leadership simply run stretches and runs. Seemed like a no brainer. You would not believe how many parents got wind before we even took a vote and tried to shoot it down saying that it would be "unfair" to the kids who were not elected captain. One said I was doing it for my son (rigged I guess?). I did it anyway and got a bunch of emails because of course my son and an assistant's son were elected by the kids (because they were the best, most well liked and hardest working I assume). We rotated a few other kids in later in the season and it seemed to work. Louder dugout and more investment in the games.
I also wanted to do helmet stickers which some have mentioned. We happened to have the same name as a great ACC college football program so I was able to get some sweet stickers online. I set criteria for getting stickers--multiple hit games, extra base hits, key play, great pitching work, great practice day, unselfish play etc. Each game I made notes and handed out stickers at the next practice. At the end of the season, yeah some kids had a ton and some had just a few. I tried to come up with excuses along the way to hand them out and it was still uneven, just like the talent on the team. No kids had any issue with this to my knowledge. Of course, the parents would send me emails about this, which I ignored. One guy apparently left over the helmet stickers..(which was fine by us as he was gone anyway). A few years later we are playing (and murdering) his team where his kid plays SS and bats first, of course, and I notice that they have helmet stickers and his son has about twice as many as anyone else. No joke.
Next year the Mike Matheny letter went out with commitment letters. No problems after that until I stopped coaching.
Point being this is the society we live in this is how parents see things. You cannot ask them for permission or let them run your team.
