Douglas Charles Marrone (born July 25, 1964) is currently the offensive line coach and assistant to the head coach of the Jacksonville Jaguars. He was previously the head coach at Syracuse University from 2009 to 2012 and the Buffalo Bills head coach from 2013 to 2014, compiling a career college football record of 25–25 and an NFL record of 15–17. Before that he served as offensive coordinator for the New Orleans Saints from 2006 to 2008.
Marrone was born in the Bronx. He was a three-year letterman at Syracuse University, playing from 1983-1985 on the offensive line; he returned to graduate from the university in 1991. He played with the Miami Dolphins in 1987 and the New Orleans Saints in 1989, and was with the London Monarchs of the World League in 1991.
On December 11, 2008, he was chosen as Syracuse University's head football coach after the 2008 season by athletic director Daryl Gross. He is the first Syracuse alumnus to serve as head football coach since Reaves H. Baysinger in 1948. Prior to being hired at Syracuse, Marrone served as an assistant coach for numerous universities and organizations since 1992 including a stint with the New Orleans Saints as an offensive coordinator from 2006 to 2008.
Reportedly, alumni such as Tim Green and Floyd Little wanted Marrone from the moment Robinson was fired, and when interviewed by Green, it was learned that Marrone had kept a folder of current high school players in the Syracuse area to get a head start in recruiting.
In Marrone's first season the Orange finished with 4 wins, one more than the previous year. The Orange doubled that output the following season. The 8 wins in 2010 was the most since 2001 for the Orange. The 2010 season was highlighted with a victory over a Top-25 West Virginia Mountaineers team and a victory in the first ever Pinstripe Bowl in New York City. Their victory in the Pinstripe Bowl was the Orange's first bowl win since 2001.In 2011, the team started 5-2, which included a win over then #11 West Virginia Mountaineers. After the 5-2 start, the Syracuse Orange failed to win another game in the season, resulting in a 5-7 record for the season. 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 the West Virginia Mountaineers.
In 2014, the Buffalo 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 10 years (The last time was in 2004, when the Bills finished 9-7 under Mike Mularkey). At the end of the 2014 season it was revealed that Marrone had a three-day out clause in his contract, in which he could resign and still collect his full 2015 salary. Marrone exercised the out clause and resigned on December 31, 2014.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 after opting out of his contract with the Bills; his interview did not go well.
