Bears coach Matt Nagy on Thursday announced a revamped offensive staff, with the additions of Bill Lazor as offensive coordinator and John DeFilippo as quarterbacks coach, as well as Dave Ragone's promotion from quarterbacks coach to pass game coordinator.
The Bears had already announced earlier this month that they had hired Juan Castillo as offensive line coach and Clancy Barone as tight ends coach.
Other staff promotions announced Thursday included Brian Ginn to assistant special teams coach, Chris Jackson to assistant wide receivers and Shane Toub to defensive quality control.
Lazor possesses 13 years of NFL coaching experience with six different teams, working primarily as an offensive coordinator and quarterbacks coach.
Lazor most recently spent three seasons with the Bengals, first as quarterbacks coach (2016) and then as offensive coordinator (2017-18). In 2018, Cincinnati's offense finished third in the NFL in red-zone touchdown percentage (71.1) and boasted a 1,000-yard rusher (Joe Mixon) and 1,000-yard receiver (Tyler Boyd).
In 2017, Lazor took over play-calling duties after Week 2 for an offense that featured receiver A.J. Green, who was voted to his seventh straight Pro Bowl after catching 75 passes for 1,078 yards and eight touchdowns.
In 2016, Bengals quarterback Andy Dalton was named to his third Pro Bowl after passing for 4,206 yards, the second most in franchise history.
Prior to his tenure in Cincinnati, Lazor spent two seasons as Dolphins offensive coordinator in 2014-15. In 2014, Miami averaged 24.3 points and 350.1 yards per game, the most in both categories by the Dolphins since 1995.
Quarterback Ryan Tannehill passed for 4,045 yards and 27 touchdowns, the most by a Dolphins quarterback since Hall of Famer Dan Marino had 30 in 1994. And Lamar Miller rushed for 1,099 yards and eight TDs.
In 2015, receiver Jarvis Landry caught 110 passes for 1,157 yards and four touchdowns.
Lazor spent one year as Eagles quarterbacks coach in 2013. He tutored Nick Foles, who had the best season of his NFL career, passing for 2,891 yards with 27 touchdowns, two interceptions and a league-leading 119.2 passer rating.
Lazor has also worked in the NFL as an offensive quality control coach with the Falcons (2003), offensive assistant and quarterbacks coach with the Redskins (2004-07) and quarterbacks coach with the Seahawks (2008-09).
Lazor has worked on NFL staffs headed by Joe Gibbs, Mike Holmgren and Dan Reeves, who have combined to win six Super Bowls.
Lazor was a three-year starting quarterback at Cornell. He began his coaching career at his alma mater as an assistant from 1994-2000. He has also coached collegiately at Buffalo (2001-02) and Virginia (2010-12).
DeFilippo, meanwhile, boasts 22 years of coaching experience, including 15 in the NFL. In 2018, he was interviewed for the Bears' head-coaching job that ultimately went to Nagy.
DeFilippo spent the 2019 season as Jaguars offensive coordinator. He helped rookie quarterback Gardner Minshew throw for 3,271 yards with 21 touchdowns, six interceptions and a 91.2 passer rating while also rushing for 344 yards.
Prior to that, DeFilippo served as Vikings offensive coordinator in 2018 and Eagles quarterbacks coach in 2016-17. Philadelphia won the Super Bowl in 2017, thanks in large part to quarterbacks Carson Wentz and Nick Foles.
Wentz was named second-team All-Pro despite missing the final three games with a torn ACL. He completed 60.2 percent of his passes for 3,296 yards with 33 touchdowns, seven interceptions and a 101.9 passer rating that ranked fourth in the NFL.
Foles replaced the injured Wentz and threw for 971 yards and six touchdowns with a 115.7 rating in three postseason contests. Foles earned MVP honors in Super Bowl LII after passing for 373 yards and three TDs with a 106.1 rating in a 41-33 win over the Patriots.
DeFilippo joined the Eagles after spending the 2015 season as offensive coordinator with the Browns. In Cleveland, he helped quarterback Josh McCown post an impressive 93.3 passer rating.
DeFilippo originally entered the NFL as an offensive quality control coordinator with the Giants (2005-06) before serving as quarterbacks coach with the Raiders (2007-08) and Jets (2009).
DeFilippo left the NFL to work as quarterbacks coach at San Jose State in 2010 before adding the title of offensive coordinator in 2011. He returned to the NFL for a second stint as Raiders quarterbacks coach from 2012-14.
In 2014, DeFilippo helped develop second-round draft pick David Carr, whose 348 completions were the second most ever by an NFL rookie quarterback and whose 12 interceptions were the fewest by a rookie with at least 450 pass attempts in league history.
DeFilippo started his coaching career at the collegiate level at Fordham (2000) before moving on to Notre Dame (2001-02) and Columbia (2003-04).
Ragone becomes passing game coordinator after spending the past four seasons as Bears quarterbacks coach. Over the past two years, Ragone has helped quarterback Mitchell Trubisky post a 19-10 record as a starter while throwing for 6,361 yards and 41 touchdowns.
Trubisky was named to the Pro Bowl in 2018 after helping lead the Bears to the NFC North championship with a 12-4 record. Starting 14 games, he passed for 3,223 yards with 24 touchdowns, 12 interceptions and a 95.4 passer rating.
Prior to joining the Bears, Ragone worked for the Titans as receivers coach (2011-12) and quarterbacks coach (2013) before serving as an offensive quality control coach with the Redskins in 2015.
