After that, there was a string of unsuccessful stints by a number of coaches. Amarillo High went 16 years, 1960–1975, without gaining the playoffs. Bum Phillips, who would later become the Houston Oilers head coach, coached Amarillo at the beginning of that drought, from 1959 to 1961. In 1975, Larry Dippel arrived, turning the program around and guiding the Sandies to 222 wins until 2005. Dippel took over an Amarillo High program in 1975 that was struggling. AHS had not been in the playoffs since 1959 but Dippel turned around the program and led AHS to 23 playoff appearances. After the 2005 season (31 seasons), Dippel retired. He finished his career with a record of 253-134-6, with 222 of the wins coming with the Sandies. His many honors include being named 2003 National Coach of the year, serving as president of the Texas High School Coaches Association in 1999 and being named state coach of the year (The Tom Landry Award) in 1993. Dippel also earned the Sportsmanship Award from Amarillo Football Officials four times. Dippel's tenure as a head coach at Amarillo High is the longest of any head coach in any sport in AISD history. He won 16 district titles at Hereford and AHS combined, and he led the Sandies to the Class 5A state semifinals in 1992. Dippel leaves having coached fathers and sons, uncles and nephews.
