Edgerton, in his second year as an assistant coach at Barton County CC, helped his men earn a share of the national title at the 2021 NJCAA Division I Outdoor Track & Field Championships. The Cougars had multiple scorers in both the 100 and 200 and finished runner-up in both the 4×100 and 4×400 relays. Edgerton’s athletes starred a few weeks earlier at the NJCAA Region VI Championships, scoring 96 points and winning every event shorter than 800 meters.
