Monday's NFL matchup between the Baltimore Ravens and Los Angeles Chargers marked the third time Ann Arbor brothers John and Jim Harbaugh have faced off as head coaches.

John, the Ravens' head coach since 2008, holds a 3-0 record against his younger brother Jim, who is in his first season leading the Chargers. Jim previously served as head coach of the San Francisco 49ers from 2011 to 2014, and the two Harbaughs famously met in Super Bowl XLVII, where John emerged victorious.

Before their coaching careers, the brothers played together on the same high school football team. In 1979, the Ann Arbor Pioneer team finished with a 4-5 record, with John as a senior defensive back and Jim, a sophomore quarterback, starting the year on the junior varsity team.

After high school, John attended Miami (Ohio) and eventually began his coaching career. After his sophomore year of high school, Jim followed his father Jack to Palo Alto, Calif., when Jack took a coaching job at Stanford. The Harbaughs' roots in Ann Arbor ran deep, and Jim would later return to Michigan, where he played and, in 2023, led the Wolverines to a national championship as head coach. Jim Harbaugh played 14 seasons in the NFL before moving on to coaching, taking snaps with the Chicago Bears, Indianapolis Colts, Baltimore Ravens and San Diego Chargers. 

The Harbaugh brothers were inducted into the Ann Arbor Pioneer Athletics Hall of Fame together in 2016.
