The Seahawks hired Mack Brown as tight ends coach on February 22, 2024. Brown previously spent five seasons with the N.Y. Jets; three as an offensive assistant, after two seasons as a defensive assistant.

Last season, Brown's tight end room was highly productive. AJ Barner set single-season highs in receptions (52), receiving yards (519), and touchdowns (6), emerging as a reliable target for QB Sam Darnold. Barner caught four passes for 54 yards in Super Bowl LX, including a 16-yard touchdown—the first TD of the game—helping Seattle secure the win. Brown also played a key role in developing rookie Elijah Arroyo, who started four of the 13 games he appeared in during the regular season.

In 2024, Brown was instrumental in the development of rookie AJ Barner, who finished the season with 30 receptions for 245 yards, while making six starts. Barner recorded a catch in 13 consecutive games, the longest streak by a rookie tight end in franchise history. Noah Fant tallied 500 receiving yards for the fourth time in his career despite missing three games.

In 2023, Brown was part of a staff that helped RB Breece Hall accumulate a team-high 1,585 yards from scrimmage, the most by a Jet since Curtis Martin's franchise-record 1,942 in 2004. Hall passed another milestone with 190 total yards vs. the Patriots, the fourth time in his career he has reached that mark in a single-game. Those four games with more than 190 total yards rank first in Jets history over a two-year span. TE Jack Conklin reached career-highs in receptions (61) and yards (621). WR Garrett Wilson finished his sophomore season with 1,042 receiving yards, three touchdowns and a career-high 95 receptions. He became the first Jets receiver in franchise history to start a career with consecutive 1,000-yard seasons.

Brown worked primarily with the wide receivers in 2022, including serving as the interim wide receivers coach for the last three games. Wilson led all rookies in receptions (83) and receiving yards (1,103), earning AP NFL Offensive Rookie of the Year honors, edging out Seahawks RB Kenneth Walker III.

In 2021, his first on the offensive side with the Jets, Brown worked primarily with the wide receivers as five different Jets receivers caught at least 25 passes, the only such team in the league, while four had multiple touchdown receptions. Following the season, in the 2022 Senior Bowl, Brown coached wide receivers on the National Team.

Working primarily with the linebackers in his first two seasons (2019-20), New York's defense allowed just 99.5 rushing yards per game, the fourth-best average in the league.

Prior to joining the Jets, Brown spent the previous three seasons as the offensive coordinator/quarterbacks coach at Missouri State, helping the Bears increase their scoring average in consecutive seasons.

Before Missouri State, Brown served on the staff at Missouri, starting as a recruiting assistant before adding the role of offensive quality control/graduate assistant. He began his coaching career as an assistant coach at William Jewell College, before moving on as the offensive coordinator and quarterbacks coach at Lawrence (Kan.) High School.

As a quarterback at Baker University, Brown was a first-team All-HAAC performer in 2008 and a three-time NAIA Academic All-American, helping lead the Wildcats to their first NAIA playoff berth in 15 years. He finished with school records for most passing yards in a career, season, and single-game.

Brown completed a master's degree in health, physical education, and recreation from Emporia State in 2011. He and his wife, Amanda, have one son, Reed, and one daughter, Quinn.
