I bet the Hispanic girls are significantly shorter.
Woman's (girls) volleyball is sexy so they all want to show for the boys. This is what it's all about. The Hispanic girls feel left out by being relegated to B status... so are the butt of boy's jokes (just my guess)
When I was in HS, we had four white girls from the same family playing. The oldest was a SR my sophomore year and the youngest a freshman when I graduated. The shortest was 6' 1" and they had to duck to get on and off the bus.
If you play be percentages, they’ll be shorter and heavier. But proclaiming as much would be, well, you know...
