Steve Spagnuolo

On January 24, 2019, Spagnuolo was named defensive coordinator for the Kansas City Chiefs. Spagnuolo previously coached defensive backs and linebackers under Chiefs coach Andy Reid in Philadelphia from 1999 to 2006. On February 2, 2020, Spagnuolo won his 2nd championship as the Chiefs beat the 49ers 31-20 in Super Bowl LIV.

On January 15, 2015, Spagnuolo rejoined the New York Giants as defensive coordinator, serving under head coach Tom Coughlin in 2015 and then under head coach Ben McAdoo in 2016. The Giants finished 30th in the NFL for defense his first year back, but rebounded to have the league's second best defense in 2016, which fueled the team to an 11-5 record. Spagnuolo became interim head coach of the Giants after a house cleaning by the organization after the firings of McAdoo and General Manager Jerry Reese on December 4, 2017. He led them to a last-game win against the Washington Redskins, but finished 1-3 as interim head coach. After the season, Spagnuolo was not retained by new head coach Pat Shurmur, as Shurmur elected to hire James Bettcher as his defensive coordinator.

Baltimore hired Spagnuolo as a senior defensive assistant before the 2013 season, then promoted him to assistant head coach/secondary coach in 2014.

Spagnuolo learned under Philadelphia defensive coach Jim Johnson, and shares the same aggressive, blitz-heavy approach as his mentor. (He did not incorporate this philosophy during his time in New Orleans however). Spagnuolo uses a 4–3 base defense with a heavy emphasis on multiple blitz packages, including corner and safety blitzes. While defensive coordinator of the New York Giants, he often used a smaller defensive line, with three or even four defensive ends to further pressure the quarterback.

Spagnuolo's first season saw the Rams go 1–15, the worst record in the league and the worst season in franchise history. After rebounding to 7–9 in 2010, they regressed to 2–14 in 2011, tied with the Indianapolis Colts with the worst record in the league. Spagnuolo was fired on January 2, 2012, after compiling a 10–38 overall record in his three seasons in St. Louis, the second-lowest winning percentage for a non-interim coach in franchise history.

On January 19, 2012, Spagnuolo agreed to terms with the New Orleans Saints to become the new defensive coordinator under head coach Sean Payton, choosing this position rather than an offer from the Philadelphia Eagles. However, Payton was subsequently suspended for the season for his alleged role in the New Orleans Saints bounty scandal, leaving Spagnuolo to coach the defense without Payton's input. In 2012, the Saints allowed the most yards for a season of any defense in NFL history en route to finishing 7–9 and missing the playoffs for the first time in four years. Soon after Payton's suspension ended, Spagnuolo was fired on January 24, 2013.

On February 7, 2008, he took his name out of consideration for the head coaching position of the Washington Redskins. The same day, the New York Giants made Spagnuolo one of the highest-paid defensive coordinators in the NFL with a new three-year contract, worth roughly $2 million a year.

Following another successful season in 2008 in which the Giants finished the season 12–4, but lost in the Divisional round of the NFL Playoffs, Spagnuolo's name came up as a replacement for numerous head-coaching vacancies. These vacancies included, the Denver Broncos, New York Jets, and Detroit Lions,, but Spagnuolo decided to join with the St. Louis Rams, taking over their head-coaching vacancy with a 4-year, $11.5 million contract. Spagnuolo hired Pat Shurmur and Ken Flajole to be the Rams' offensive and defensive coordinators respectively. Spagnuolo then hired Josh McDaniels to be the team's offensive coordinator to replace Shurmur, who left for the Browns' head-coaching job.

In January 2007 he was hired as the defensive coordinator for the New York Giants under head coach Tom Coughlin.

This philosophy proved successful, with the Giants leading the NFL in sacks in 2007. In Super Bowl XLII, Spagnuolo's defense sacked Tom Brady five times, which was the most he had been sacked in any game that season.

Spagnuolo began his NFL coaching career in the Philadelphia Eagles organization in 1999, serving as linebackers and defensive backs coach. He remained there for eight years.
