Dalton was also the head coach for the Montreal Alouettes of the Canadian Football League (CFL) from 1967 to 1969, tallying a mark of 7–31–4.
After not being retained by Chuck Knox, Dalton held the same position with the Kansas City Chiefs under Marv Levy, another former Alouettes coach.
After Levy was fired, he moved to the Houston Oilers coaching staff as offensive coordinator under Ed Biles, Chuck Studley, and Hugh Campbell.
In 1989, he became the offensive coordinator at the University of Northern Colorado, a position he would hold for 11 years before his promotion to head coach.
Quarterback Corte McGuffey won the Harlon Hill Trophy as the NCAA Division II college football player of the year in 1999.
