For me and my perspective, the lower level games can be an enigma at times.
I love the lower levels because the kids are still young enough that they usually play hard all game long from start to finish and are eager to try to learn the game.
As I was telling our AD after our last game this weekend, It's just frustrating to encounter adults that thing it's all about them and not the kids. Coaches who feel that the rule requiring no starters in with a 30 point lead; officials who show no mechnics, no hustle, or admit they don't know and/or won't enforce the league specific rules; and the parents who think their child will be the next pro superstar even though the kid is 10 year old are enough to make anyone (myself included) ask themselves "Why am I at these games?"
I also realize that what happens in a CYO JV game with players in the 9-10 year old range is small potatoes in the grand scheme of life, the people involved -- coaches, game crew (such as myself), etc. -- should at least try to give a good effort and try to do as good a job as possible and ensure the games are played according to the rules (ideally, not just to the letter, but also in the spirit). Yes, I will admit I am a bit particular about subs coming to the timer/scorer to check in and not just waiting at the far ends of the table, but only because I want to get them in the good habits early.
