Montana

Early years (1897–1934)

The University of Montana's first football season was in 1897, when the team played six games; they won a single game, against future rival Montana State. The team played only schools from Montana until it helped found the Northwest Intercollegiate Athletic Association (NWIAA) in 1902. In addition to Montana, this original Northwest Conference included Washington, Washington State, Oregon, Oregon State, Idaho, and Whitman College. Despite the association's stated goal of increasing intercollegiate athletics, Montana continued to play only the nearest teams. Unfortunately, the team would not win a game against a Northwest Conference opponent until a 10-0 win over Washington State in 1914.

In 1915, the Northwest Conference had become superfluous with the creation of the Pacific Coast Conference, which by 1924 already included the five public Northwest Conference schools from Washington, Oregon, and Idaho, in addition to California and Stanford. Montana joined the conference in 1924 and remained there through the 1949 season. Montana won only nine conferences games (8–16 against rival Idaho), and never played a home game against a team from the state of California.

No team was organized in 1918, due to World War I and the 1918 flu pandemic.

Doug Fessenden era (1935–1948)

(46–40–4) Record, (9–1) vs. Cats
Doug Fessenden was the first Montana coach to last more than five years, and of those who coached more than two years, he was the first to end his career with a winning record.

The program was on hiatus for the 1943 and 1944 seasons, due to World War II. Of the six teams in the northern division of the PCC, only Washington continued through the war.

Mountain States (Skyline) Conference era (1951–1961)

In 1948, the Montana board of education announced that it was de-emphasizing athletics at the state university. Key to the university's decision was the feeling that continued affiliation with the PCC was incompatible with the goal to "keep intercollegiate athletics properly subordinated to the academic function" and they would "seek to develop competition in all sports with institutions similar in purpose, size, resources and academic standing." The conference was only "preferable to having no conference affiliation."

In 1951, Montana joined the Mountain States Conference, popularly known as the Skyline Conference, and competed there until the conference dissolved in the summer of 1962. The Grizzlies never had a winning season in the Skyline and never won more than three games until 1960. In 1963, Montana joined Gonzaga, Idaho, Idaho State, Weber State, and Montana State in forming the Big Sky Conference. (Gonzaga dropped its football program after 1941 and Idaho did not compete in conference play until 1965.)

Jack Swarthout era (1967–1975)

(51–41–1) Record, (3–6) vs. Cats
Montana's football struggles continued in the new Big Sky Conference, and the team had only won nine games in its first four seasons when school officials decided that a coaching change was needed. Following a 1–9 season in 1966, University of Montana president Robert T. Pantzer announced in December the hiring of Jack Swarthout, a former quarterback/halfback/end from Montana. Swarthout brought on Jack Elway as an assistant and they improved the team immediately to 7–3 in their first season. Within two years, Swarthout guided the team to back-to-back undefeated regular seasons in 1969 and 1970, and Montana's first Big Sky Conference titles. At the end of both years, they were defeated by North Dakota State in the Camellia Bowl, which was part of a set of bowls that determined the NCAA Football Championship Subdivision national championship, prior to the current FCS playoff structure.

Continued success was expected, but a disappointing season in 1971 was followed by a work-study scandal that eventually led to Swarthout's resignation. In 1972, a federal grand jury returned a 32-count indictment charging five university officials and coaches (including Swarthout) with conspiring to illegally use federal-aid money to pay for fictitious jobs for athletes. Though Swarthout was found not guilty, the charges hurt recruiting and the student-body government decided to withdraw financial support for athletic programs. Despite the controversy and resultant performance decline, Swarthout is credited as being the coach that turned Montana into a winning football program.

Don Read era (1986–1995)

(85–36) Record, (10–0) vs. Cats
After Swarthout's departure, Montana would register only one winning season over the next 10 years. In November 1985, Montana fired coach Larry Donovan and replaced him with Portland State's head coach, Don Read. Over the next 10 years, Montana would go 85-36, have 10 straight winning seasons, and was undefeated against cross-state rival Montana State. Read would win 2 conference titles, make the FCS playoffs 5 times and win Montana's first national championship.

Mick Dennehy era (1996–1999)

(39–12) record, (4–0) vs. Cats
Mick Dennehy had been the offensive coordinator under Don Read and was promoted to head coach when Read retired in 1995. Dennehy continued Montana's success, making it to the national championship in his first year for a rematch against Marshall University. This time, however, Montana lost 49–29. Montana made the playoffs every year under Dennehy and continued to beat Montana State, but they did not make it past the first round of the playoffs after his first season. After the 1999 season, Dennehy accepted a head coaching position at Utah State.

Joe Glenn era (2000–2002)

(39–6) Record, (2–1) vs. Cats
The Joe Glenn era began with high hopes for the winner of two Division II championships at the University of Northern Colorado. He did not disappoint, making it to the national championship in his first two seasons, where he won it in his second appearance. Unfortunately, during Glenn's third year, Montana's win streak against Montana State finally came to end at 16 straight games. Glenn left after the 2002 season to pursue the head coaching job at the University of Wyoming.

Bobby Hauck era (2003–2009)

(80–17) Record, (5–2) vs. Cats
Bobby Hauck began his tenure in 2003, and over the next 7 years would win a share of the Big Sky Conference title every year. His teams made it to the national championship game three times but lost each game including in 2004 (lost to JMU), 2008 (lost to the University of Richmond), and 2009 (lost to Villanova University). After the 2009 season, Hauck left to take the head coaching job at UNLV. He returned as head coach in 2017 after leaving UNLV and being an assistant for San Diego State.

Robin Pflugrad era (2010–2011)

(13–7) Record, (1–1) vs. Cats
In 2009, Robin Pflugrad returned to Montana to become the wide receivers coach under Bobby Hauck. After that season, Hauck left Montana to become the head coach at UNLV, and Pflugrad was promoted to replace him. Pflugrad said after his hiring that Montana would be "very fast on offense, up-tempo and upbeat." Pflugrad led Montana to a Big Sky Conference title and a national semifinal appearance in 2011, but those were vacated by the NCAA on July 26, 2013 due to infractions which included a nationally publicized rape scandal. Individually, Pflugrad was hit with numerous sanctions by the NCAA for his part in the infractions.

Mick Delaney era (2012–2014)

(24–14) Record, (2–1) vs. Cats
Mick Delaney was hired July 26, 2012, replacing former head coach Robin Pflugrad. On July 26, 2013, the NCAA found the Montana football program guilty of multiple major infractions and one secondary infraction. None of these infractions occurred while Delaney was the head coach. Delaney retired after three seasons.

Bob Stitt era (2015–2017)

(21–14) Record, (1–2) vs. Cats
On December 16, 2014, the university announced that Bob Stitt would be replacing former head coach Mick Delaney after he announced his retirement. Bob Stitt started his tenure at Montana with one of the most memorable games in Griz football history with a 38–35 win over the 4-time Defending FCS National Champions North Dakota State thanks to an 80-yard, 1:37 scoring drive to end the game.

Bobby Hauck era, part two (2018–present)

(25–11) Record, (2–3) vs. Cats
Hauck returned to Montana for the 2018 season. Montana earned its 200th win at home against Sacramento State on September 22, 2018, 41-34.

On September 4, 2021, Montana upset the #20 ranked Washington Huskies. It was their first win against Washington since 1920 and only their second overall win in 20 games against the Huskies. It was also the fifth occasion a FCS team beat a ranked FBS team since the 1978 FBS/FCS split.
