Lunney Jr. began his coaching career as a
graduate assistant coach during the
1998 and
1999 seasons at Arkansas before moving to
Tulsa for the
2000,
2001, and
2002 seasons as
quarterbacks (2000-2001) and
wide receivers (2002) coach. He then moved on to be the co-
offensive coordinator and quarterbacks coach for
San Jose State for two seasons, the last of which the Spartans ranked 17th in the NCAA in passing offense. From 2005 to 2012, Lunney Jr. was the offensive coordinator and quarterbacks coach for
Bentonville High School in
Northwest Arkansas, during which time the team won six conference titles and two state championships.
Arkansas From the
2013 to the
2019 season, Lunney Jr. was the
tight ends coach and recruiting coordinator for in-state recruits at Arkansas. From 2014-2016, Lunney developed one of the top tight ends in Arkansas history in
Hunter Henry, who won the John Mackey Award and was a consensus first-team All-American as a junior in 2015. On November 11, 2019, Barry Lunney Jr. took over as interim head coach for Arkansas, following the firing of former head coach
Chad Morris. During his tenure as interim head coach, Arkansas lost at eventual national champion #1
LSU, and at home to Missouri.
UTSA Lunney was named associate head coach, offensive coordinator and quarterbacks coach at
University of Texas at San Antonio (UTSA) on December 13, 2019. Prior to UTSA's matchup against
Louisiana in the
2020 First Responder Bowl, UTSA head coach
Jeff Traylor tested positive for
COVID-19. Lunney served as acting head coach for the game. UTSA lost the game, 31–24, finishing the season at 7–5. The
2021 UTSA Roadrunners football team compiled a record of 12–2. They won the
Conference USA West Division championship, before defeating
Western Kentucky in the
Conference USA Football Championship Game, 49–41, to claim the program's first conference title. UTSA ended the season at the
Frisco Bowl, where they lost to
San Diego State, 38–24. UTSA's offense, under Lunney, averaged 442.9 total yards, 254.3 passing yards, 188.6 rushing yards, and 37.8 points per game.
Illinois In December 2021, Lunney was hired as the offensive coordinator for the
Illinois Fighting Illini football team by former Arkansas head coach
Bret Bielema. Illinois would finish the season 8-5 after losing to Mississippi State in the Reliaquest Bowl. Under Lunney's play-calling, Illinois' offense averaged 379.1 yards per game, 211.8 yards passing, 167.3 yards rushing, and 24.2 points per game. It was Illinois' first bowl game appearance since 2019, and their first winning season since 2011. During the 2022 season, Lunney Jr. agreed to a one-year contract extension through the 2025 season, given in large part because the Illini were one of the most improved offenses in the Big Ten. The contract extension also increases Lunney's salary from $675,000 per year to $800,000 beginning in 2023 and $825,000 in each of the following two years. After a down year in 2023 when the Illini finished 5-7, Illinois bounced back in 2024 to finish 10-3 and beat South Carolina in the
2024 Citrus Bowl. Lunney Jr's offense averaged 211.2 passing yards per game, 153.6 rushing yards per game, and 28.3 points per game. Illinois is off to a 4-1 start to the 2025 season. Lunney Jr's offense is averaging 242.6 yards passing, 133.4 yards rushing, and 35.8 points per game. ==Head coaching record==
