Chris Hewitt enters his seventh season leading the Ravens' secondary, which has posted the NFL's third-best pass defense (219.7 ypg) since 2015. Promoted to pass defense coordinator prior to the 2020 campaign, Hewitt's units have helped the team earn standout defensive rankings each of the past several years. In 2020, Baltimore allowed the NFL's second-fewest points (18.9) and seventh fewest yards (329.8) per game. The Ravens also owned the second-ranked third-down defense (34.0%) and produced a league-high 25 FFs. In 2019, Baltimore achieved a franchise-best 14-2 record and second-straight AFC North division title. The defense allowed the NFL's third-fewest points per game (17.6), ranked fourth in yards per game (300.6) and was No. 6 vs. the pass (207.2 ypg). Baltimore's 6 defensive TDs in 2019, including 5 by defensive backs, tied (with '06 and '08) for the second most in franchise history (2004 – 7) and also tied (TB) for the most in the NFL. Pro Bowl CBs Marlon Humphrey and Marcus Peters each made multiple game-changing plays, scoring 2 defensive touchdowns each. Baltimore also recorded the NFL's second-best defensive passer rating (77.5). In 2018, the team was the top-overall defense, allowing an NFL-best 292.9 yards per game. Against the pass, Baltimore ranked fifth, allowing 210.0 yards per game, while its 80.6 defensive passer rating stood second, only behind the Bears' 72.9 mark. Baltimore also permitted the league's second-fewest points per game (17.9), just behind Chicago (17.7) in 2018. The Ravens were also among the best in other key defensive categories that season, including ranking third in third-down defense (34.1) and fourth in rushing yards allowed (82.9 ypg). Over the past five seasons (2016-20), the Ravens have allowed the second-fewest points per game (18.7), the fourth-fewest passing yards allowed (217.0 ypg), recorded the fourth-most (tied) interceptions (75), and posted the third-most takeaways (126) in the NFL. In 2017, Baltimore's defense racked up an NFL-best 22 INTs, while also tying for the lead (KC & SD) in 2016 with 18 INTs. The 2017 Ravens also forced an NFL-high 34 turnovers and finished with the league's No. 1 turnover differential (+17). Baltimore's pass defense finished 10th (213.8 ypg), while its defensive passer rating (72.4) was the NFL's second-best mark. In 2016, the Ravens also forced 28 turnovers, tying (Ari. & SD) for the NFL's fourth most. In 2015, Baltimore's defense allowed the NFL's eighth-fewest yards per game (337.4), finishing No. 2 overall (291.1 ypg) and No. 1 against the pass (183.3 ypg) during the season's final eight games. Hewitt joined the defensive coaching staff in 2014, a year when the Ravens allowed the NFL's sixth-fewest points (18.9 ppg) and eighth-fewest yards per game (336.9), even though Baltimore's secondary was hit hard by injuries, with six DBs (five CBs and one safety) being placed on Injured Reserve.
