JACKSONVILLE, Fla. — John DeFilippo got his first NFL job working for Tom Coughlin, serving as a quality control coach for the New York Giants in 2005-06.

Fourteen years later, and with a resume that includes tutoring Mark Sanchez and Carson Wentz as rookies and winning a Super Bowl with backup Nick Foles, DeFilippo has returned to Coughlin’s regime.

The Jaguars hired the former Minnesota offensive coordinator to the same position Wednesday, hoping he can help revitalize one of the league’s least-productive offenses.

Coach Doug Marrone announced the addition of DeFilippo along with five other assistant coaches. DeFilippo replaces Nathaniel Hackett, who was fired in late November and landed in Green Bay.

The Vikings parted way with the 40-year-old DeFilippo in mid-December, reportedly for failing to commit to the run ground game. DeFilippo spent less than a year in Minnesota. The Vikings hired him after two seasons in Philadelphia, where he was praised for his work as quarterbacks coach with Foles and Wentz. DeFilippo had one previous NFL stint as an offensive coordinator, in Cleveland in 2015.

“High energy on field, a tough football coach, going to hold people accountable,” Marrone said.

DeFilippo will be tasked with improving an offense that ranked 27th in yards and 31st in points in 2018. He also could play a role in developing the team’s next quarterback, something he did with Sanchez, Wentz, Foles, Oakland’s Derek Carr and even Minnesota’s Kirk Cousins.

The Jaguars have failed repeatedly to find a long-term solution at the all-important position, coming up short with Byron Leftwich, David Garrard, Blaine Gabbert and Blake Bortles. The Jags are expected to move on from Bortles before March, draft a quarterback and sign a veteran to potentially start until the rookie is ready.
