1 - how do you open up hockey? Support adult rec league programs. Without those, the kids won't be as interested.
2 - drop the checking penalty from the womens game. Yes, I said it. Most of the women grow up playing with the boys anyway. And the penalty? Slows the game down.
3 - Do not market those pink jerseys as much. And open up the sizing because not all women are stick figures.
Note: These are all strictly my opinion.
