Schellenberg’s association with the Roughriders dates back to 2015, when he was a Training Camp Assistant for the first of four consecutive springs. After camp wrapped up in 2018, he remained with the organization on a seasonal basis as a Football Research and Development Assistant. He was hired as a full-time Video and Analytics Co-ordinator shortly after the 2021 CFL season.

Schellenberg excelled in football and basketball at Regina’s Luther College High School before accepting a football scholarship and attending Idaho State University for the 1994-95 academic/athletic year. He then returned to his home province and joined the University of Saskatchewan Huskies. He played university basketball and football for one year before concentrating on the latter sport. In 1996, he helped the Huskies football team win the Vanier Cup.

With the Huskies men’s basketball team, Schellenberg was an assistant coach from 2002 to 2014. As well, he was the Director of Basketball Development with Basketball Saskatchewan Inc., from 2007 to 2013. In 2010, he was an assistant coach with a Canadian under-17 male basketball team that won a bronze medal at the inaugural FIBA under-17 championship.

Since 2016, Schellenberg’s company (Gameplan Data Inc.) has been providing U Sports teams with extensive data for their games.
