Manhasset HS is rife with nepotism? Maybe it is - and I'd guess it works for some and not others. There are favorites everywhere. I have no idea if her niece and friends are better than your daughter and her friends, maybe they are, maybe they're not. At every competitive high school, kids are vying for spots. If the coach thinks certain kids are better, then they'll play. Same as at my kid's high school. It's high school, not everyone gets a trophy. Get over it.
