Sean McVay effect

Los Angeles Rams head coach Sean McVay is the namesake of the term.

The Sean McVay effect is a term used to describe a trend beginning in 2018 regarding the hiring practices of National Football League (NFL) teams towards employing young head coaches that specialized in offensive strategy, but would later be expanded to describe the trend of hiring young head coaches in general. The phrase originates from Los Angeles Rams head coach Sean McVay, who when hired at 30 years old in 2017, became the youngest NFL head coach in the Super Bowl era (1966–present). McVay rapidly changed the culture of the organization and turned the Rams into the league's highest-scoring offense, resulting in the team becoming perennial title contenders and eventual champions in Super Bowl LVI. In light of McVay's quick success, NFL teams increasingly began to hire relatively younger coaches.

Background

McVay in 2014 with the Washington Redskins

On January 12, 2017, the Los Angeles Rams hired Washington offensive coordinator Sean McVay, who was then 30 years old, as their head coach. He began his NFL career in 2010 as Washington's assistant tight ends coach before working his way up to becoming their offensive coordinator, a role he held for three years. ^[1] His hire by the Rams made McVay the youngest NFL head coach since 1938, when Art Lewis became coach of the Cleveland Rams at 27 years old. Prior to McVay's hiring, the four youngest head coaching hires in the Super Bowl era (1966–present) – Lane Kiffin, Raheem Morris, Dave Shula, and Josh McDaniels – had a combined win–loss record of 52–115 before being fired by their respective teams. ^[2]

McVay took over a Rams team that finished the 2016 season last in points, total yards and first downs, and that were later ranked as the second-worst offense of the 2010s. ^[3] Under McVay's new leadership, the Rams led the league in total offense in 2017, making them the first team in the Super Bowl era to go from last to first in total offense in a single season. ^[4] In addition to McVay's coaching acumen, many noted how he was able to change the culture of the organization with his willingness to engage with players and take accountability for his own shortcomings. ^{[5] [6]} The Rams would reach the playoffs in McVay's first season, ending a twelve-year postseason drought for the franchise. ^[7] McVay received recognition from the league and the media for turning around the team's fortunes, and at the season's conclusion he became the youngest-ever recipient of the AP NFL Coach of the Year award. ^{[8] [9]}

The following season, McVay's second with the team, the Rams returned to the playoffs and won the 2018 NFC Championship Game against the New Orleans Saints. At age 33, this made McVay the youngest head coach to lead his team to the Super Bowl. ^[1] The Rams ultimately lost Super Bowl LIII to the New England Patriots. ^[10]

Coaching hiring trends after McVay

Following McVay's quick turnaround of the Rams, many NFL teams sought to replicate the strategy of hiring a young head coach that specialized in offensive strategy. ^[11] Journalist Mark Maske of The Washington Post coined the term "Sean McVay effect" in the 2018 offseason, after McVay's first year as a head coach, in reference to the fact that both Kansas City Chiefs offensive coordinator Matt Nagy (39) and Philadelphia Eagles quarterbacks coach John DeFilippo (39) were expected to receive head coaching interviews. Maske cited McVay's instant success in his debut season as the reason the pair were receiving serious considerations, and stated that the two would have had to wait years for such opportunities under the previous circumstances. ^[12] Nagy would soon be hired as the head coach of the Chicago Bears. ^[13]

Matt LaFleur, Zac Taylor, and Kliff Kingsbury were hired in 2019 as NFL head coaches to emulate McVay's success. LaFleur and Taylor had worked under McVay on the Rams.

In the wake of the Rams' continued success and Super Bowl appearance during McVay's second year, the subsequent 2019 offseason had several more hires in the mold of McVay, with Matt LaFleur (39), Kliff Kingsbury (39), Adam Gase (40), Freddie Kitchens (44), and Zac Taylor (35) all becoming the head coaches of different teams. ^[14] Many of these coaches were noted to be hired due to their connections with McVay; LaFleur had previously served as McVay's offensive coordinator, Taylor had stints as the Rams' wide receivers coach and quarterbacks coach under McVay, while Kingsbury was initially publicized as being "friends with Rams coach Sean McVay" upon the announcement of his hiring. ^{[15] [16]} A month after the 2019 season began, sportswriter Bill Barnwell quipped that "anyone who has ever worn a polo shirt around McVay is now an NFL head coach", while Taylor himself similarly mentioned years later that "I think the joke is if you ever had a cup of coffee with Sean McVay, then you're going to be a head coach in the NFL". ^{[17] [18]}

The trend of younger head coaches with offensive backgrounds has continued, with some of these coaching hires having worked with McVay in the past. ^[19] Kevin O'Connell (36) came directly from the McVay coaching tree as the Rams' offensive coordinator before becoming head coach of the Minnesota Vikings. ^[20] Liam Coen (39) had served under McVay in various roles, including assistant wide receivers coach, assistant quarterbacks coach and offensive coordinator, before being hired as the head coach of the Jacksonville Jaguars. ^[21] While Mike McDaniel (38) did not serve under McVay before being hired as head coach the Miami Dolphins, he was part of the Washington coaching staff from 2011 to 2013 alongside McVay, LaFleur and Kyle Shanahan, another relatively young offensive-minded head coach who was hired at the age of 37 by the San Francisco 49ers less than a month after McVay was hired by the Rams. ^{[22] [23]}

Eventually, this movement would also be associated to the hiring of relatively younger head coaches that focused on defensive strategy as well. ^[24] Brandon Staley (38) was hired in the 2021 offseason as head coach of the crosstown Los Angeles Chargers after spending one season as McVay's defensive coordinator on the Rams. ^[25] Upon his hiring, Staley was touted as being "the Sean McVay of defense", in that he was also a "young, bright mind that sees it all, that can communicate with people". ^[26]

Furthermore, younger coaches would also be hired for assistant roles, with the average age of NFL assistants going down two years from 2015 to 2025. ^[27] Several of McVay's lower-level assistants were regularly hired for offensive, defensive or special teams coordinator positions on other teams, including Shane Waldron, Joe Barry, Ejiro Evero, Wes Phillips, Dwayne Stukes and Matt Daniels. ^[28] Seattle Seahawks quarterback Russell Wilson reportedly favored hiring Waldron, who was then the Rams' passing game coordinator, as the Seahawks' offensive coordinator due to his experience on McVay's coaching staff and familiarity with McVay's offensive system. ^[29] Waldron was also previously considered for the Cincinnati Bengals head coaching position that eventually went to Taylor. ^[11]

Impact

Super Bowl LVI featured Sean McVay's Rams against Zac Taylor's Bengals in the youngest Super Bowl head coaching matchup in history.

Sean McVay and Cincinnati Bengals head coach Zac Taylor — aged 36 and 38, respectively — met in Super Bowl LVI on February 13, 2022. It was McVay's second appearance at the Super Bowl and Taylor's first as a head coach, although Taylor was on the Rams' coaching staff during McVay's previous appearance. ^{[30] [31] [32]} With McVay and Taylor combining for an age of 74, it marked the youngest-ever head coaching matchup in Super Bowl history. ^[33] The Rams would defeat the Bengals by a score of 23–20, resulting in McVay becoming the youngest head coach to ever win a Super Bowl. ^[30]

For decades prior to McVay joining the Rams, hiring younger NFL head coaches was rare, as twenty-two head coaches aged 40 or younger were hired from 1990 to 2016. Conversely, fifteen different head coaches in the same age bracket were hired from 2017, the year McVay was hired, to 2022, the year after he won the Super Bowl. ^[34] During the seven years before McVay was hired, only 6% of head coaching vacancies were filled by coaches in their thirties; this number grew to 36% in the seven years after McVay was hired. As a result, the average age for an NFL head coach decreased from 53.4 to 47.7 years old from 2015 to 2025. At the end of that span, NFL coaches on average would be significantly younger than the coaches and managers of the major professional sports leagues in the United States and Canada. ^[27]

This trend has also been linked to the increased turnover for head coaches in the NFL. For five years leading up to the 2025 offseason, 22 of the league's 32 teams changed head coaches, including 11 who made multiple hires during that time, with owners willing to take bigger chances with younger coaches. Jed Hughes of sports management firm Korn Ferry also attributed the increased opportunities for young coaches at the assistant level to the staff-building practices and subsequent team successes of head coaches McVay and Kyle Shanahan. Both generally hired younger coaches to their staffs, and with their young top coordinators often getting hired in the offseason, both head coaches would elevate their young lower-level assistants to fill those roles. ^[27]

Despite the trend, as well as McVay's Super Bowl win, there has been little correlation between the age of a head coach and the success of his team. From 2000 to 2024, teams with a head coach under the age 50 have a combined winning percentage of .504. Meanwhile, teams with coaches over the age of 50 have a winning percentage of .500. ^[27]

It has been noted by some that this shift of younger, offensive coaches being hired has come at the expense of older coaches and coaches that specialized in defensive strategy. ^{[35] [36] [37]} Three-quarters of available head coaching jobs went to offensive coaches between 2017 and 2019. By the end of that period only 10 out of 32 NFL coaches had defensive backgrounds. ^[38]

Others have noted that this trend has done little to support hiring candidates from ethnic-minority backgrounds, an ongoing issue in the NFL. ^{[39] [40]} During the 2019 offseason when Taylor and Matt LaFleur were hired, only one of the eight open head coaching positions went to an African-American coach. ^[39] Stephen Holder of The Athletic reported that in the 2021 season, there were more former McVay assistants serving in top positions than there were African-American head coaches. ^[41] This has also been attributed to the lack of minorities on offensive coaching staffs, as 86% of the offensive coordinators between 1999 and 2021 have been Caucasian. ^[34]
