It's sad that we have to think about liability and the coach's professionalism when all we want to do is a kind thing for another human being, especially a child.
The only thing I would worry about would be that the parents weren't home and they would come to pick her up from somewhere else, and worry she wasn't where she was supposed to be.

Hmmm, at 11 I would be okay if my son came home from practice/games with another team parent, whether I knew them well or not, with the caveat that the teammate of my child was also in the vehicle, as opposed to alone with the adult I didn't really know.
Although I will say I think if your child isn't old enough for that type of situation - they shouldn't be left at all. I coach U12 soccer so 10 and 11 yo's - I don't appreciate or respect parents who leave their kids and come back at the end of the game/practice. There are issues with injuries and game cancellations, plus suspensions (not that it's happened yet, but a kid who gets carded and kicked out of the game has to actually leave, he can't stay there waiting for a ride). All parents should be staying OR making their own arrangements with a teammate parent they know and feel comfortable with to cover in any of these situations.
