I know EXACTLY what you're talking about.
As girls coaches, we're pretty flexible, trying to grow girls hockey.
If I could get the 5 squirts and 2 peewees (one is my kid) to every girls game, they would be unstoppable.
...those girls who do play with girls and with boys are learning two games, and really developing a wide array of hockey skills.
Boys team coaches are borderline inflexible to rigid. I get it--they have to be that way because boys and their parents need pretty firm guidelines. You. Here. Now.
They are also spoiled in that they typically get single-sport kids. Johnny plays hockey for 5 months out of the year, coach tells him to be somewhere, he shows up.
Not only do we compete with that, but all the myriad other activities girls are simultaneously into.
Last year, we had to compete with and schedule around squirts schedule, peewees schedule, bantam schedule, U19 schedule, swimming, ballet, tap, freestyle skiing, violin, church, indoor soccer, ski racing, basketball, volleyball, and driver's training. You can't tell them to do anything, it's a delicate negotiation.
We're raising well-rounded and independent-minded young ladies (sweet spot), but FOOK, it's like herding cats in the here and now (vent). In the big picture, we're doing it right.
