From 1946 to 1947, Curfman was the head coach at New Mexico A&M, then in the Border Conference, where he compiled an 8–11 record. He resigned in December to work in the sporting goods industry in Texas, then joined the staff of third-year head coach Dixie Howell at Idaho in February 1949.[2][3] Two years later, Howell and Curfman submitted their resignations in March 1951,[4] and Curfman remained on campus as an interim coach for the upcoming 1951 spring drills. The administration was impressed with his handling of the team during the first week of practice and hired him as head coach in mid-April.[5] He guided the Vandals for three seasons in the Pacific Coast Conference and compiled a .278 record.[6] His salary in his final year at Idaho in 1953was $7,920.[7]
Curfman made headlines during the 1953 season as his overmatched Vandals struggled in conference play in the PCC.[8] Following his resignation as Idaho head coach in December,[9][10][11] he was hired as the business manager for the Spokane Indiansminor league baseball team in January 1954.[12]
He later coached high school football back in Texas, at Pampa (1958–1961) and Pecos (1962–1964).[13]
Curfman died at age 77 in 1993 in Tucson, Arizona; he and his wife are buried at the East Lawn Palms Cemetery in Tucson.
