University career
Mueller joined the Regina Rams for the 2007 season, dressing for all eight regular season games and both playoff games as the team's second-string quarterback.[1] In 2008, Mueller dressed for all eight regular season games and the team's Canada West semifinal game at Calgary as a backup quarterback.[1]
2008 was Teale Orban's last year of eligibility playing university football. Mueller took over from him as the starting quarterback for the 2009 season,[2] and started all eight of the team's regular season games and the team's one playoff game. That year, he set a Rams single-season record with 310 pass attempts, also led the Canada West Conference in pass completions (176) and yards (2308). Mueller threw for a Rams postseason record with 470 passing yards in the team's Canada West semifinal game at Saskatchewan on November 7.[1]
In 2010, Mueller once again started all eight of the Rams regular season games and the team's one playoff game. He set a Ram single-season record in pass completions (182) and led the conference in passing yards (2437). Mueller was named the Canada West Offensive Player of the Week after throwing two touchdown passes and rushing for two more in a 40-8 win over Alberta on October 2.[1]
Mueller's 2011 season was cut short when he suffered a season-ending injury on the team's second play from scrimmage against UBC on September 2. Because of his injury, he was granted a medical redshirt.[1]
In 2012, Mueller started six regular season and both playoff games at quarterback for the Rams. He engineered a game-winning touchdown drive against Manitoba that spanned nine plays and 95 yards. He was injured at the beginning of that drive and missed the team's next two games. In the Rams' Canada West Semifinal win on November 2 against Saskatchewan, Mueller was named the Canada West and CIS Offensive Player of the Week after completing 21 of 32 passes for 393 yards and three touchdowns.[1]
Mueller finished his career as the Rams' all-time leader in pass completion rate (62.1%), second on the team's all-time list in career pass completions (511) and passing yards (6522), and third in touchdown passes (34).[1]

Mueller signed as an undraftedfree agent with the Edmonton Eskimos of the CFL on May 9, 2011, following the 2011 CFL Draft.[3] He saw game action in Edmonton's first preseason game, a game played in Regina against his hometown team, the Saskatchewan Roughriders. In that game, Mueller was 3 for 3 passing for 45 yards.[4] He was released on June 20, 2011 and returned to the Rams.[5]

From 2015 to 2019, Mueller was the Stampeders' running backs coach.[8][9] During that span, Calgary went to the Grey Cup in 2016, 2017, and 2018, with the team winning in 2018.
