When Natalia Chavez hit a buzzer-beater to help her high school win the New Mexico Girls State Basketball Championship last year, fans knew right away that her shot was precisely 45 feet 5.5 inches. That’s because the tournament was using ShotTracker, a sensor-based technology that provides real-time data, such as how many times a player touched the ball and who was the most effective at defense. The technology is common in college and professional sports, but this was its first appearance at the high school championship level. Experts predict it’ll spread to more high school sports, including football and hockey. Some argue that such monitoring raises privacy issues and could add undue pressure for young athletes. “We have to weigh the pros and cons,” says Karissa Niehoff, executive director of the National Federation of State High School Associations. But she believes it’s “a great example of how technology can make the experience better for all involved without compromising the integrity of how the sport is played or providing an advantage to one team or the other.”
