I have noticed some schools are now starting to have youth and little league coaches on staff, and in a few cases, head coaches. Bringing that all-star team type mentality to high school. I know schools have to meet MSHSAA standards, but private schools may hire more coaches that don't have education degrees.
One of the biggest changes I have noticed in my years of education and coaching is youth sports used to just be for a few months, and you played with kids from your or the very neighboring town. Nowadays you have kids playing on teams that may be hours away, playing on teams with none of their school mates. Volleyball, softball, baseball, baseketball particularly.
