LOUDOUN COUNTY, Va. – The Washington Redskins finalized their 2017 coaching staff today, announcing the addition of Chris O'Hara as Offensive Quality Control as well as formal title changes for Bill Callahan (Assistant Head Coach/Offensive Line Coach), Chad Grimm (Outside Linebackers Coach) and Bret Munsey (Assistant Special Teams Coach).

"We've assembled a staff of quality teachers and quality people," Redskins Head Coach Jay Gruden said. "As a group, we're excited to work together to achieve our goals for the 2017 season."

O'Hara joins the Redskins after having spent the last three seasons as an offensive coaching associate with the Jacksonville Jaguars. In 2015, the Jaguars' offense accounted for 35 touchdown passes, shattering the previous team record of 28 set in 2007.

Before entering the NFL ranks, O'Hara spent three seasons on the defensive side of the ball at the University of Miami from 2011-13, including one season as a graduate assistant and two as a student assistant. In O'Hara's final season with the Hurricanes, the Miami defense ranked third in the ACC with 27 takeaways and helped propel linebacker Denzel Perryman to first-team all-conference honors. 

Prior to working at Miami, O'Hara spent two seasons at Temple University, serving as a student assistant with the school's football team. A native of Swoyersville, Pa., O'Hara graduated from Miami in December 2012 with a degree in sports administration.

Callahan originally joined the Redskins as the team's Offensive Line Coach on January 15, 2015. He is entering his 19th NFL season in 2017 as part of a career that includes head coaching stints at both the pro and collegiate levels. In the team's first two seasons under Callahan from 2015-16, the Redskins allowed 50 total sacks after allowing 58 sacks in the 2014 season alone.

Grimm is entering his ninth NFL season after spending the last two years serving in a defensive quality control capacity for the Redskins. Last year, he assisted current Defensive Coordinator Greg Manusky with the team's outside linebackers, helping oversee a unit that produced the team's top three leaders in sacks in 2016 (Ryan Kerrigan, 11.0; Trent Murphy 9.0, Preston Smith 4.5).

Grimm is the son of Russ Grimm, a Pro Football Hall of Famer and three-time Super Bowl champion who stands as one of the most decorated players in Redskins history. Russ – a founding member of the franchise's famed "Hogs" – played 11 seasons in Washington from 1981-91 and served in various assistant roles for the team from 1992-2000.

Munsey is entering his fourth season with the Redskins after assisting on special teams and overseeing special projects since 2014. Last season, he helped a number of Redskins special teamers turn in notable performances. With 34 field goals on the year, kicker Dustin Hopkins broke Mark Moseley's team record of 33 field goals set in 1983. In addition, the Redskins finished the season with an 11.9-yard punt return average, fourth-best in the NFL, marking the team's first finish in the Top 5 in punt return average since leading the league in the category in 1995.
