Scoring: The Mustangs scored a total of 217 points across ten games, averaging 21.7 points per game.
Home Field: All home games were played at Mustang Stadium, which has undergone multiple renovations since 1983 and is now known as Alex G. Spanos Stadium.
Opponents: The schedule included matchups against teams such as UC Davis, San Diego State, and Portland State, all of which were competitive Division I and II programs.

Season Structure and Game Schedule

The 1983 season followed a traditional college football calendar, beginning in early September and concluding in mid-November. Cal Poly operated as an independent, meaning it was not bound to a conference schedule and had full control over its opponent selection.

Season Start: The Mustangs opened the season on September 10, 1983, with a loss to San Diego State, a Division I-A (now FBS) team.
Key Win: A notable victory came on October 15, when Cal Poly defeated Humboldt State 31–14 in a non-conference matchup.
Defensive Performance: The defense held opponents to under 20 points in five games, showcasing improved consistency compared to previous seasons.
Offensive Leader: Quarterback Mark Erne was a key offensive contributor, throwing for over 1,200 yards and nine touchdowns during the season.
Final Game: The season concluded on November 12 with a loss to UC Davis, finishing the year on a two-game losing streak.
Postseason: The team did not qualify for the NCAA Division II playoffs, which required a conference championship or at-large bid—neither of which was achieved.

Comparison at a Glance

The following table compares the 1983 Cal Poly Mustangs season to adjacent years in terms of record, coaching, and scoring output:

Season	Overall Record	Head Coach	Points Scored	Postseason

1983	6–4	Joe Harper	217	None

The 1983 season marked a transitional year for the program. While the team showed resilience under Harper’s return, it lacked the consistency needed for a postseason berth.
