Team sports fever is in the air with the Summer Olympics in recent memory and the World Series coming. Nowhere is the fever more fervent than in high schools. My grandniece is committing her energy to her track team’s grueling practices. My grandson, who attends an arts high school in a film-making program, is bemoaning his school’s lack of a soccer team (his beloved sport). My granddaughter, a cellist who’s just graduated from LaGuardia School of the Arts, has always claimed orchestra as her team sport.
