Eberle served as the head football coach at New Hampshire College of Agriculture and the Mechanic Arts[a] for 1912 and 1913, compiling an overall record of 5–8–1. He was also the head basketball coach for the 1912–13 season, tallying a mark of 5–5. Eberle was apparently well-liked by students—the college yearbook recounted that at the close of his first year, "the entire student body was at the station to cheer him off as a token of their appreciation for his services to New Hampshire."[4]
Eberle later was head basketball coach at Swathmore, compiling a 10–2 record for the 1915–16 basketball season.[5] He was a college football on-field official for multiple seasons, through at least 1922.[6]
Eberle married Anna Oppenlander in November 1914. He died in May 1967, at the age of 80.[7]
