Syracuse University On December 11, 2008, after the 2008 season, Marrone was chosen as Syracuse University's head football coach by athletic director
Daryl Gross. He was the first Syracuse alumnus to serve as head football coach since
Reaves H. Baysinger in 1948.
2009 In
Marrone's first season, the Syracuse Orange finished with four wins, one more than the previous year.
2010 The Orange doubled that output the
following season. The eight wins in 2010 were the most since 2001 for the Orange. The 2010 season was highlighted with a victory over
Kansas State and a victory in the first ever
Pinstripe Bowl in New York City. This was the Orange's first bowl win since 2001.
2011 In
2011, the team started 5–2, which included a win over then No. 11
West Virginia. After the 5–2 start, the Orange failed to win another game in the season, ending with a 5–7 record.
2012 In
2012, Marrone coached the Orange to an 8–5 record, and a share of the Big East title as the result of a four-way tie. Their 38–14 victory in the
Pinstripe Bowl again came against
West Virginia.
Buffalo Bills On January 6, 2013, Marrone was chosen to succeed
Chan Gailey as head coach of the
Buffalo Bills. His overall record during his two seasons as head coach of the Bills was 15–17. During his Bills' tenure, Marrone nicknamed himself "Saint Doug," referring to the fact that it takes two miracles to be canonized as a saint (he believed winning at Syracuse was one miracle and winning at Buffalo would qualify as the other). In 2014, the Bills finished with a record of 9–7, second place in the
AFC East and two wins away from making the playoffs. This was the Bills' first winning season in ten years (when the Bills finished 9–7 under
Mike Mularkey in 2004). At the end of the 2014 season, it was revealed that Marrone had a three-day "out" clause in his contract in the event of an ownership change; the clause was triggered by the sale of the Bills in 2014 after the death of the Bills' founder and long-time owner
Ralph Wilson. Marrone exercised the out clause and quit on December 31, 2014, and still collected his 2015 salary in full. After Marrone quit, several players expressed their displeasure and disgust with both the decision and the way that he informed the team. One of the captains and the longest-tenured player on the team, running back
Fred Jackson, said it was "like getting punched in the stomach." Marrone interviewed with the New York Jets for their head coaching position; his interview reportedly did not go well.

Gus Bradley. He coached the final two games of the 2016 season. In 2017, the Jaguars won the
AFC South and made the playoffs for the first time since the
2007 season. On January 7, 2018, the Jaguars won their first playoff game under Marrone, defeating the
Buffalo Bills 10–3 in the
Wild Card Round. The Jaguars then upset the
Pittsburgh Steelers in the
Divisional Round, advancing to the
AFC Championship Game, where they were defeated by the
New England Patriots by a score of 24–20. On February 23, 2018, the Jaguars extended his contract through 2021. On January 4, 2021, Marrone was fired after the Jaguars finished the 2020 season with a 1–15 record. He finished his tenure in Jacksonville with a record with a playoff record for a career record of .
