If you want to drive young girls away from hockey, this is a great mentality.
Just let them play coed and it will be an "equal" playing field for all.
Right now you have 8 PAHL organizations fielding 20 girls only teams from 10U thru 19U (with a 19U division that includes a 16U team).
I know a lot of those organizations have to double roster kids on both the 12U and 14U teams in order to fill out entire rosters, so you can have *barely* enough teams to keep the divisions running. The rule change wording even acknowledges "this will likely be a step backwards in a few places and therefore could cost us a small number of girls teams." The rule about double rostering for girls to play on two teams is somewhat unfortunate necessity. It is not like these girls are taking roster spots away from other girls on those teams, there are just not enough players to go around.
I suspect another onus for these proposed rule changes is parents on birth year PAHL teams being upset about talented girls who play 10U and 12U Pens Elite girls while also playing on the AA coed teams for the PAHL. Sometimes they may have to pick and choose which team they play for on a tournament or for a certain weekend, and that gets the other parents upset.
Every person is different, but most girls I've seen and known playing hockey seem to thrive on the competition playing with and against the boys at their age plus enjoy the comradery and sense of fitting in with their girls teams as well. Limiting their choices and number of teams that organizations are even able to field for them as options to satisfy some legal sense of obligation of gender equality really goes against the mission and objective of making hockey fun, fair, and accessible to as many young people who want to participate as possible.
If any of you have any influence on the organizations or people in organizations voting on these proposed rules, if you care about the present and future of girls hockey in the region, I would strongly urge you to vote "no" on these changes.
