Football was first played on the Cal Poly campus in 1916. At that time, Cal Poly was a vocational school, as it did not become a four-year college until 1941.
1915 to 1940s: The beginning The California Polytechnic School played mostly high school teams and college freshmen teams for its first 16 seasons. In 1933, the Mustangs enjoyed their first undefeated season under coach
Howie O'Daniels. During the 1933 campaign, the Mustangs did not allow a single point during that season. Cal Poly officially became a four-year school in 1941 and posted a 5–3–1 record under O'Daniels. Football was put on hold during
World War II ('43 and '44) and resumed in 1945.
1950s: Jeter, Madden, Beathard leave legacy Under coach
LeRoy Hughes, Cal Poly experienced its second undefeated season in 1953. In the decade of the 1950s, the Mustangs posted a record of 67–29–1. During this time, All-American
Stan Sheriff became Cal Poly's first player to join an NFL roster, beginning with the
Pittsburgh Steelers in 1954. Hughes' teams also included future
Chicago Bears running back
Perry Jeter and future
Pro Football Hall of Fame inductee
John Madden, who was known as a bruising tackle. Upon graduation, Madden was drafted by the
Philadelphia Eagles. Of Jeter, legendary Bears founder
George Halas commented in 1954: "Never have we received a more accurate appraisal (in promotional assessment) of a player than LeRoy Hughes gave us on Jeter." Joining Madden and Jeter on the Mustang roster was quarterback and defensive back
Bobby Beathard, who would be inducted into the Pro Football Hall of Fame in 2018 as the architect and general manager responsible for building the
Washington franchise into a perennial Super Bowl-winning and contending dynasty.
1960s: Tragedy strikes Cal Poly; Harper brought on Tragedy struck in 1960 following a game at
Bowling Green State University on Saturday, October 29, 1960, when a plane leaving Toledo Airport crashed, killing 22 people. This included 16 Mustang football players and the team manager. The next seven seasons produced a 22–45 record.
Joe Harper, then a
Colorado assistant, was hired as Mustang head coach on February 7, 1968. Harper, a former offensive guard for
UCLA (1956–58), directed Cal Poly to 7–3 and 6–4 seasons to end the decade, respectively. In the final year of the decade, Cal Poly upset
Fresno State 21–17, leading the
Mustang Daily campus newspaper to publish a rare all-capped double-truck headline declaring the game as "One of the Greatest Wins in Poly Grid History". At the time, Harper told the
Fresno Bee the win was "the greatest game I have ever been involved with." The result also made the sports section of the
San Francisco Chronicle, which noted the Mustangs' first win over the Bulldogs in 12 years.
1970s: Harper builds a dynasty Under Harper, Cal Poly produced an 8–0–1 regular-season record in 1972 and received a trip to the
Camellia Bowl to play in the Western Regional Championship Game of the NCAA's
College Division. Cal Poly was ranked No. 3 in the division by both the AP and UPI polls heading into the postseason. They would end up losing 38–21 to the
University of North Dakota (
North Central Conference co-champs) in the bowl game hosted in Sacramento's
Hughes Stadium, telecast regionally on
ABC. In 1978, the Mustangs would make it to the NCAA Division II playoffs but lost to
Winston-Salem State. Another highlight during the decade was Cal Poly's most recent football victory over
Fresno State, which came 26–0 on Oct. 6, 1979. The score marked, at the time, the first shutout in the 57-year history between the two programs. Mustang safety Chris Jones had two interceptions in the game, while fullback Paul Dickens led the offense by rushing for 163 yards on 35 carries. Each of the ten Mustang football teams in the 1970s posted a winning season.
1980s: Mustangs win national title 1980 would be one of the most memorable seasons for the Cal Poly Mustangs, as they went on to win the
NCAA Division II National Football Championship under Harper. Cal Poly
defeated Eastern Illinois in the championship game on
ABC and would finish the season with a 10–3 record that included a win over eventual-
Division I-AA national champion
Boise State. Never before or since has a D-II team defeated the eventual I-AA national champion and won a D-II national title in the same year. During the 1980 season, running back
Louis Jackson led the nation at the Division II level with 1,424 rushing yards on 287 carries.
Robbie Martin, who starred in the NCAA championship win, compiled a career punt-return average of 16.9 yards per runback, graduating after the 1980 title season with the third-best PR average in division history at the time. Following the national title, the Mustangs were honored with a parade through downtown
San Luis Obispo on December 15, 1980. The parade traveled down Higuera Street before a rally held in Mission Plaza. Then-mayor Lynn Cooper spoke at the celebration. On November 20, 1982, Cal Poly's Clarence Martin set an all-time Division II single-game record for most yards per kickoff return (minimum of three returns), averaging 71.7 yards (215 total) on his three KRs vs. then-rival Pomona. The record was finally broken after 39 years by Carson-Newman return specialist DeQuan Dudley in 2021.
1990s: The move to Division I In 1990, coach
Lyle Setencich would lead the Mustangs to another playoff appearance before losing in the second round to powerhouse
North Dakota State. The 1990 Mustangs yielded just 11.3 points per game, the best defensive average throughout Division II for the year. The defensive front was led by lineman Pat Moore, who received an invitation to the
NFL Scouting Combine after compiling 67 tackles and 9.5 sacks during the 1990 season. Also aiding the defense was
punter Doug O'Neill, who in 1991 led the nation in punting average, with 45.1 yards per punt, while earning first-team All-American honors from the
AP. In 1994, Cal Poly would make the jump to
Division I-AA (now Football Championship Subdivision) with head coach
Andre Patterson at the helm. The Mustangs would see moderate success, posting a 7–4 record in Patterson's first year followed by two 5–6 seasons before Patterson departed for a position as an NFL line coach. In 1997, Larry Welsh took over the program and led the Mustangs to a 10–1 record and a
national ranking of 18th. The season was highlighted by a 38–35 win at
FBS-level
New Mexico State. However, still only in its fourth year in the I-AA ranks at the time, Cal Poly was not extended an invitation to the
national playoffs. Welsh (a 2017 inductee to the
CIF Southern Section Hall of Fame) would follow that season with three 3–8 seasons and was not contractually renewed by then-athletic director John McCutcheon. The 1997 team's omission from the postseason was referred to as a "snub" by the
Los Angeles Times following the regular season. The 1997 squad finished ranked No. 16 in the TSN Division I-AA media poll and No. 17 in the
USA Today coaches Top 25. Cal Poly quarterback
Alli Abrew compiled a passer-efficiency rating of 179.5 in 1997, leading the nation at the I-AA level.
2001–2008: Rich Ellerson era Rich Ellerson, credited by
Sports Illustrated for his role in refining
Arizona's versatile "Desert Swarm" defense featuring
Tedy Bruschi, was introduced as Cal Poly's new head coach on December 6, 2000. In 2001, his first year, he led the Mustangs to a 6–5 season. Two years later, the program earned its second modern-day win over an
FBS opponent, routing
UTEP 34–13 on September 6, 2003. Coach Ellerson would emphasize defense and, by 2004, not only did his 9–2 Mustangs secure their first of three
Great West Conference football titles, but
linebacker Jordan Beck would win the
Buck Buchanan Award as the nation's best defensive player in the
NCAA Division I Football Championship Subdivision. In 2004, Beck led the nation at the Division I-AA level in both solo tackles per game (8.82) and forced fumbles per game (0.55). Following a 6–0 start to the 2004 season, Cal Poly found itself ranked ahead of 32
FBS-level teams in the
Jeff Sagarin NCAA Football Ratings, an index which combined all Division I-A and I-AA programs into one ranking system. Fan interest crested as the Mustangs moved to 7–0, with the upcoming week's rivalry game against UC Davis sold-out on campus well in advance of game day (ultimately won by the Aggies, snapping Cal Poly's win streak despite breaking then-stadium attendance records in back-to-back games). In 2004, the Mustangs ranked No. 1 in the country for rushing defense, giving up 84.3 yards per game on the year. During the next two years, Cal Poly would experience continued success on the field and another NCAA first as two more players would win the Buchanan Award:
Chris Gocong in 2005 and Kyle Shotwell in 2006. In 2005, the 9-4 Mustangs also earned their first FCS playoff berth and victory with a
35–21 win over Montana. A key to the playoff victory over the Grizzlies was running back James Noble, who scored four touchdowns in the game. (Noble had arrived at Cal Poly after setting the
San Bernardino County single-season rushing record, amassing 2,256 yards at
Barstow High in 2003, fourth-most in the entire state.) Cal Poly was then knocked out in the quarterfinals by
Texas State on
ESPN2 in a 14-7 defensive battle. Gocong's 23.5 sacks during the 2005 season remain an all-time FCS/I-AA single-season record. The 2008 season would prove to be another exciting season for the Mustangs, whose victories included a road win over FBS
San Diego State (the program's second in a three-year stretch) as well as a heartbreaking 36–35 overtime loss to the bowl-bound
Wisconsin Badgers in Madison. The
2008 Mustangs also made the playoffs but lost a shootout in the first round against
Weber State. The 2008 season saw Cal Poly lead the country in both total offense at the FCS level, totaling 487.5 yards per game, and total scoring (44.4 points per game). One of several keys to the prolific offense was
center Stephen Field, selected as an All-American in back-to-back seasons. During the 2008 season, Cal Poly matched its
highest ranking in the FCS to date, voted No. 3 in The Sports Network poll on November 4, and maintaining the No. 3 ranking over the next three weeks. During the year, student-printed T-shirts were distributed in the student section declaring "Throw it to Ramses!" in reference to the team's record-breaking wide receiver,
Ramses Barden. Barden, as well as cornerback
Courtney Brown, Gocong, defensive back
David Richardson, defensive back
Asa Jackson and Beck were all developed by Ellerson and his staff during the decade and all joined
NFL rosters after being drafted or signing as free agents. At the conclusion of the 2008 season, with three conference titles, two postseason appearances, multiple All Americans developed and a record of 56–34, Ellerson departed California's Central Coast as he accepted an offer to become the head coach of
Army. As of 2021, Barden still held the all-time FCS/I-AA record for consecutive games during a career with a TD catch (20, from 2007 to 2008).
2009–2019: Tim Walsh era In 2009,
Tim Walsh, the offensive coordinator for the
Army Black Knights during the 2007 and 2008 seasons, was hired as Cal Poly's 16th head coach. On November 12, 2011, Cal Poly set an all-time single-game FCS/I-AA record for most team rushes, running 95 times for 405 yards against Eastern Washington. helped lead Cal Poly to a share of the 2012 Big Sky Conference football title before going on to play for the
San Diego Chargers and
Tennessee Titans in the NFL. The 2012 season proved to be the most successful of Walsh's coaching career, as his Mustangs finished 9–3, in a three-way tie for the
Big Sky Conference football title and earned and an
NCAA FCS playoff invitation. During the year, the Mustangs picked up a 24–22 win over FBS-level
Wyoming. Cal Poly fell in the first round at
Sam Houston State, 18–16. During the 2012 season, Cal Poly peaked in the
national FCS rankings at No. 11 on October 22, although the
Jeff Sagarin Ratings ranked the Mustangs second in the FCS in the week of October 24. Midway through the 2012 season, running back Deonte Williams was added to the
Walter Payton Award Watch List. In 2014, Cal Poly quarterback Chris Brown became the first player in the school's Division I-era history to throw for a touchdown and score TDs on both a run and a reception in the same game, as he achieved the rarity in a 30–24 victory at Weber State. The Mustangs
returned to the playoffs in 2016 with a 7–4 record. On October 15, 2016, Cal Poly set a Big Sky single-game record for passing accuracy, as former
MaxPreps National High School Player of the Year Dano Graves led a 13-of-14 day for a .929 completion percentage in a 55–35 win over Portland State. During the 2016 season, Cal Poly was ranked as highly as
No. 14 in the FCS STATS poll, on both October 24 and October 31. They lost in the first round to the University of San Diego, 35–21. Following the 2016 season, Walsh was awarded a five-year contract extension; however, after going 1–10, 5-6 and 3–8, Walsh elected to retire following the 2019 campaign with a 59–66 record while at Cal Poly. In 2018, Cal Poly's Joe Protheroe led the country in rushing yards at the FCS level, gaining 1,810 yards on 363 carries. The 2018 season also saw Cal Poly defensive back Dominic Frasch lead the nation in passes defended (a statistic which combines interceptions and pass breakups) for the year in the FCS, totaling 19. Also in 2018, Mustang quarterback Khaleel Jenkins set an all-time single-season Big Sky Conference record for TD/pass attempts/INT ratio, not throwing any interceptions among his 89 passes (nine of which went for touchdowns, including four to
J. J. Koski, who went on to play for the
L.A. Rams).
2020–2025: Baldwin to Wulff era Former
FCS national championship-winning Eastern Washington head coach
Beau Baldwin was announced as Cal Poly's new head coach on December 11, 2019. Baldwin, who coached
Cooper Kupp at EWU, began to implement a
"multiple" offensive scheme, and Cal Poly thereafter saw its passing yardage per game increase by 52.1 percent from 2019 to the shortened 2021 spring season, and then increase by another 18 percent in the fall of 2021. The program dealt with multiple starts, stoppages and restarts to practice schedules amid COVID-19, going a combined 2-12 during the next 24 months overall, beginning with the lack of a traditional spring calendar in 2020. Senior linebacker Matt Shotwell was named to the Associated Press All-American Third Team in December 2021. Two Cal Poly freshmen, edge
Elijah Ponder and punt returner Giancarlo Woods, were selected to the
Phil Steele Magazine Freshman All-America Team in January 2022. Then, in April 2022, Cal Poly held its first uninterrupted spring practice season in three years. In June 2022, a replacement of the then-
Alex G. Spanos Stadium field was completed, as Cal Poly joined the rest of its peers in the
Big Sky as having a turf surface. The conversion was assisted by Diversified Project Services International.Cal Poly started the 2022 season 1-1, with quarterback Jaden Jones winning the
Big Sky Conference Offensive Player of the Week award for September 12. Jones, however, who began the year with a 5-to-0 touchdown-to-interception ratio, was lost to a season-ending leg injury during the third week. Midway through the year, the university announced the upcoming addition of a
John Madden Football Center, a total $30-million training facility adjacent to the stadium, set to complete construction in 2024. The 30,000-square-foot facility will furnish a new locker room, weightlifting stations, a nutrition area, study lounge and film-review theater. during a 2023 Big Sky Conference win. Meanwhile, the Mustangs also suffered more injuries across the lineup, and started a combined seven total backup linemen the rest of the fall, ultimately finishing 2–9 in closing the year with a 49–42 victory over
Portland State. Baldwin then accepted a position as
offensive coordinator at
Arizona State early in the offseason, and incumbent assistant
offensive line coach
Paul Wulff was promptly elevated to head coach on December 6, 2022. One of the team leaders in 2022 was wide receiver
Chris Coleman, selected to the
East-West Shrine Bowl 1000 watch list in the preseason, before going on to finish with 939 receiving yards. Coleman signed an undrafted free-agent contract with the Miami Dolphins in late April 2023.
2026–present: Skipper era On December 3, 2025,
Tim Skipper was named the 19th head coach at
California Polytechnic State University, San Luis Obispo. ==Affiliation history==
