Change the system rather than play a style that does not fit the personnel. Teach girls to bounce back when adversity stares them in the face. Do not over-coach. It isn't what you tell them, it is what you get them to do. Instill pride and desire.
Little things can make a great team.
A basketball game is a series of mistakes. The team making the fewest mistakes will be most likely to win. Profit by your mistakes. A little done well is better than a lot done poorly.
