After a 2-5 start to the season, the Jacksonville Jaguars have fired offensive coordinator Greg Olson. The Jaguars are currently ranked as the worst rushing team per game in the NFL (72.6) and have a -71 point differential in the first half of games this season. Jacksonville has promoted former Buffalo Bills offensive coordinator Nathaniel Hackett to serve as the team's offensive coordinator going forward. Hackett has been serving as the team's quarterbacks coach this season. Hackett worked as the Buffalo Bills offensive coordinator during the 2013 and 2014 seasons. Hackett's 2014 season showed both statistical improvements from season one and a winning record for the Bills, just their second since 1999. Hackett was also a former offensive coordinator at Syracuse under current Jaguars assistant Doug Marrone during the 2011 and 2012 season. Some sources have speculated that Marrone could be the potential next head coach for Jacksonville if Gus Bradley is fired at the end of the season. Hackett had also been rumored to be a potential replacement for Marrone at Syracuse after his departure to the NFL. Instead Hackett joined Marrone's staff in Buffalo, while Marrone's defensive coordinator Scott Shafer took over the head coaching reigns for the Orange. The Jaguars return to the field November 6th on the road against Kansas City.
