In 1988, a high school football team in Odessa, Texas, was so good that it became the inspiration for a book, movie and, eventually, the television series “Friday Night Lights.” And in the decades since, as West Texas has weathered the unsettling undulations of the oil industry, football has remained steady. So after the pandemic hit, the town did what it could to make sure the season wasn’t disrupted. And at Odessa High School, where the football team struggles to compete against local rivals, the members of their award winning marching band were relieved they could keep playing. In Part 2 of Odessa, we follow what happened when the season opened — and how the school weighed the decision to start against the possible risks to students’ physical and mental health.
