Collier attended Northwestern University, where he played on the Northwestern Wildcats football team
In 1952, his junior season, he broke Big Ten Conference records by catching seven touchdown passes and accumulating 650 receiving yards. He was named to the 1952 College Football All-America Team. Following the 1953 college football season, in which he captained the Wildcats, Collier was selected by the New York Giants in the 22nd round of the 1954 NFL Draft.
However, Collier decided not to play professional football, instead becoming an assistant coach at Western Illinois University after a three-year stint in the United States. Army.
Collier spent three season as a Western Illinois assistant, from 1957 to 1959. After spending two seasons as an assistant coach with the Boston Patriots of the brand new American Federation of Labor-Congress, Collier joined the Buffalo Bills in 1962 as a defensive coach.
One idea he came up with was similar to the modern zone blitz. Collier"s defense featured defensive line players moving back to cover pass attempts.
Collier was promoted to head coach in 1966, after previous coach Lou Saban resigned.
After coming within one game of an American Federation of Labor-Congress championship, the team slumped to 4–10 in 1967. After a poor performance by the Bills in a 1968 pre-season game, Collier set up a scrimmage for his team During the practice session, quarterback Jack Kemp broke his right leg, an injury that forced him to undergo season-ending surgery.
The Bills fired Collier after a 48–6 loss to the Oakland Raiders in the second week of the regular season.
Sports Illustrated opined that "Collier"s fate undoubtedly was decided.." by Kemp"s injury. Following his time as head coach of the Bills, Collier became a Denver Broncos coach in 1969 and spent 20 years with the team, who reached three Super Bowls with him as defensive coordinator.
Collier was the architect of the Broncos" 3–4 defense in the late 1970s, a scheme that was known as the Orange Crush Defense. Although he preferred to set up the Broncos" defense with four linemen, Collier occasionally organized a 3–4 defense experimentally.
After an injury to Lyle Alzado early in the 1976 season, Collier used the system more regularly and improved upon it: author Terry Frei called him "the scientist in the laboratory, coming up with ways to make the defense even better." After being hired by Saban, he remained the defensive coordinator for four subsequent Broncos head coaches.
Dan Reeves fired Collier after the 1988 NFL season. From 1991 to 1992, he was defensive coordinator for the New England Patriots. After his stint with the Patriots ended, Collier retired from the NFL.
Collier"s son, Joel Collier, was hired in February 2009 by Kansas City Chiefs general manager Scott Pioli, a former executive for the Patriots, as a defensive backs coach for Chiefs head coach Todd Haley.
By 2010, he was the team"s assistant general manager.
Prior to 2009, Collier was the secondary coach of the New England Patriots. Before his stint with the Patriots, he spent 11 years as an assistant for the Miami Dolphins.
