MacIntyre previously served as the head football coach at San Jose State from 2010 to 2012 and at Colorado from 2013 to 2018.

From 1992 to 2002, MacIntyre held various assistant coaching positions at Davidson, UT Martin, Temple, and Ole Miss.

San Jose State also earned its first-ever BCS Top 25 ranking and first bowl game invitation since 2006.

[1][2][3] In 1975, George MacIntyre took his first head coaching position with UT Martin and became offensive coordinator for Ole Miss (the University of Mississippi) in 1978.

[4][5] After graduating from Brentwood in 1984,[6] Mike MacIntyre played college football at Vanderbilt, which was coached by his father, for two seasons as a free safety.

After his father resigned, he transferred to Georgia Tech, where MacIntyre earned a bachelor's degree in business management in 1989.

[7][8] For a year after graduating from Georgia Tech, MacIntyre worked as a logistics manager at Micros Systems.

[7] MacIntyre would then spend five seasons in the NFL starting in 2003: as the defensive backs coach of the Dallas Cowboys under Bill Parcells until 2006, then in 2007 in the same position with the New York Jets.

[15] On December 16, 2009, MacIntyre became the new head coach of the San Jose State Spartans football team, a member of the Western Athletic Conference (WAC), after Dick Tomey retired.

[16] The Spartans had just come off a 2–10 record in 2009 and had only three winning seasons since 1993, and athletic director Tom Bowen planned on making a full 85 scholarship athletes available to the football team, as Academic Progress Rate penalties limited yearly scholarships to between 67 and 72.

[19] He also planned on dropping the spread offense and expand recruiting rather than rely on junior college transfers.

[23] The coach also commented shortly before the first game of 2011 that his players benefited by learning his playbook throughout 2010 despite the one-win season.

[24] Then with the longest losing streak of Division I football, the Spartans lost 13 games in a row starting in 2010 until beating New Mexico State on September 24, 2011.

[25] San Jose State averaged 190 rushing yards per game by then, a marked improvement from years past.

[27] San Jose State's homecoming game on October 14, 2011, was nationally televised as part of ESPN's College Football Friday Primetime, and San Jose State rallied to beat Hawaii 28–27, the team's third win in four games.

[36] In 2012, MacIntyre was recognized by the Fellowship of Christian Athletes with the Grant Teaff National Coach of the Year Award for his San Jose State programs performance on and off the field.

[13] On December 10, 2012, the University of Colorado announced that it was hiring MacIntyre to replace coach Jon Embree, who was fired after two seasons.

Originally signed to a five-year contract, MacIntyre is the 25th full-time coach for the Colorado Buffaloes football program.

On November 26, 2016, MacIntyre led the Buffaloes to a 27–22 victory over Utah, clinching the first Pac-12 South Division Championship in school history.

[38] MacIntyre was named the Pac-12 Coach of the Year for 2016[39] after the Buffaloes were picked to finish last in the division prior to the season.

[42] The Bobby Dodd Trophy was given to MacIntyre for his team's on and off the field performance, including their strong academic progress rate and community outreach work.

[47][48][49][50] The Ole Miss total defense improved almost 40 NCAA ranking spots in 2019 compared to 2018.

[50] On December 9, 2021, MacIntyre was named FIU's new head coach replacing Butch Davis.
