CHT:
I think you are correctly describing a situation that is a result of numbers (not primarily gender). If this is a correct assessment, then I guess the question is how to get more, better coaches for "low-number" player groups.
Clubs have tried paying more money. My experience is that sometimes this works, sometimes it does not. I've seen great "volunteer" coaches (no pay) and lousy, highly paid coaches.
It helps if the parents are active in the process of finding coaches. Don't sit back and rely only on the DOC to find coaches. Help them identify and recruit good coaches. Teams with supportive (but not insane) parents tend to find good coaches.
My gut feel is that over the next five years, there will be more high quality coaches available for low-number groups, because more of the folks that grew up in the 1990's and early 2000's will be at the stage in their lives (school over, etc), where they have the time to take on a team.
I am not saying I have the answers. I clearly don't. These are just my thought.
