[2] Hülß came to Cologne in 1959 from his home in the Coburg district, where he had played for TSV Rossach, to study sports, geography and chemistry.
The high school teacher went back to Mainz via the VfR Nierstein station, where he took over as head coach from Gerd Menne after the winter break of the 1975/76 season.
Although he and his team finished twelfth at the end of the season, the club renounced the second division license for financial reasons and went back to the Amateurliga Südwest.
Hülß built a new team that reached the championship in 1978 but had to bow to Borussia Neunkirchen and TuS Neuendorf in the relegation round.
From 1996 to 2012, the now retired director of studies at the Mainz Schlossgymnasium was press officer for the Association of German Football Teachers.
