Matt Mattox was hired as the offensive line coach at UNT in January of 2026.

Mattox joined the UNT staff after spending the 2024 and 2025 seasons in the same role at East Carolina.

A veteran coach with 20 seasons of experience, Mattox has made stops at East Carolina, Texas, UTSA, Bowling Green, Eastern Illinois, South Florida, Tulsa and others. During his career, he has been part of eight bowl games, nine conference championship teams and two NJCAA National Championship programs.

In 2025, ECU posted a 9-4 overall record, highlighted by a win over Pittsburgh in the Military Bowl. Mattox coached an offensive line that helped the Pirates rank 19th nationally in total offense, while averaging 32.7 points per game, which ranked 24th in the FBS.

That season, Mattox played a key role in the development of First Team All-American Conference selection Jimarion McCrimon and Second Team All-Conference honoree Emmanuel Poku. ECU was one of only two American Athletic Conference programs, along with UNT, to have multiple offensive linemen earn first or second team all-conference recognition.

In 2024, Mattox’s offensive line helped ECU rank among the FBS leaders in total offense (436.4 yards per game, 24th), passing offense (253.3 yards per game, 24th), scoring offense (32.0 points per game, 34th) and rushing offense (172.4 yards per game, 50th). The Pirates recorded five 200-yard rushing performances and surpassed 500 total yards in five games. Running back Rahjai Harris rushed for 1,166 yards, the 10th most in a single season in program history and posted five 100-yard rushing games.

ECU scored 49 offensive touchdowns during the season, including 26 rushing and 23 passing, and the offensive line blocked for two five-touchdown passing performances by quarterback Katin Houser. In the Go Bowling Military Bowl against NC State, the unit provided key blocks on Harris’ go-ahead 86-yard touchdown run with 1:33 remaining in the fourth quarter to secure a 26-21 victory. Hampton Ergle, a 13-game starter, went on to play for the Toronto Argonauts of the CFL, while Dustyn Hall signed with the Las Vegas Raiders and Parker Moorer with the New York Giants as undrafted free agents.

Prior to ECU, Mattox was on staff at Ronald Reagan High School, where he helped guide the Rattlers to an 11-1 record and the 6A District 28 championship.

Mattox previously spent three seasons at UTSA, where he helped the Roadrunners win Conference USA championships in 2021 and 2022. Over that span, UTSA totaled 30 wins and appeared in three consecutive bowl games. In 2022, he served as co-offensive coordinator and offensive line coach as the Roadrunners ranked among the national leaders in multiple categories, including first downs, completion percentage, third-down conversion rate, total offense, passing offense and scoring offense. UTSA finished the season with an 11-3 record and saw 13 players earn all-conference or honorable mention recognition.

In his first season at UTSA, the Roadrunners produced a record-setting offensive campaign, finishing 7-5, placing second in the Conference USA West Division and earning a berth in the SERVPRO First Responder Bowl.

As run game coordinator, Mattox helped UTSA set school records for rushing yards, rushing yards per game, yards per carry and rushing touchdowns. His offensive line paved the way for All-American running back Sincere McCormick, the 2020 Conference USA Offensive Player of the Year, who set program single-season records for rushing yards, carries and touchdowns while finishing second nationally in rushing yards per game.

Three offensive linemen under Mattox earned second-team all-conference honors, while one was named to the Conference USA All-Freshman Team. Spencer Burford was also named to the Dave Campbell’s Texas Football All-Texas College First Team, and Ahofitu Maka was placed on the Rimington Award watch list.

In 2021, UTSA posted a 12-2 record, setting program standards for wins and winning percentage while capturing its first conference title. The Roadrunners were nationally ranked for the first time in program history and earned a bowl appearance in the Frisco Bowl. UTSA set school records for total points, points per game, first downs, total offense and yards per game, while McCormick repeated as Conference USA Offensive Player of the Year and earned multiple All-America honors.

Four of Mattox’s offensive linemen earned league recognition that season, including first-team honors for Burford, who was later selected in the fourth round of the NFL Draft by the San Francisco 49ers.

Mattox joined UTSA after spending the 2019 season at McNeese as offensive coordinator and offensive line coach, where the Cowboys improved in every major offensive category and ranked second in the Southland Conference in rushing during league play.

From 2017 to 2018, Mattox served as run game coordinator and offensive line coach at South Florida. In 2018, the Bulls ranked among the national leaders in rushing offense, total offense and scoring offense, while producing multiple all-conference performers.

Mattox also coached at Texas in 2016, Tulsa in 2015, Bowling Green in 2014 and Eastern Illinois in 2013. At Texas, he coached All-Americans Connor Williams and D’Onta Foreman, who rushed for more than 2,000 yards and won the Doak Walker Award. The Longhorn offensive line was a semifinalist for the Joe Moore Award.

At Eastern Illinois, Mattox coached an offensive line that helped the Panthers lead the FCS in total offense and scoring during a 12-2 season that culminated in an Ohio Valley Conference championship. The offense featured quarterback Jimmy Garoppolo, the 2013 Walter Payton Award winner.

Before entering the Division I ranks, Mattox spent six seasons coaching offensive line and tight ends in the junior college ranks, including stints at Coffeyville Community College and Butler Community College. During his time at Butler, the program won four conference and region championships and advanced to the NJCAA national championship game in 2010.

Mattox began his coaching career at Houston, where he served as an assistant strength coach and later as a graduate assistant. The Cougars won the Conference USA Championship and appeared in the Liberty Bowl during his tenure.

A native of Holton, Kansas, Mattox was a second-team junior college All-American tight end at Butler Community College before finishing his playing career at Houston, where he earned second-team All-Conference USA honors as a senior offensive tackle.

Mattox earned his bachelor’s degree in sports administration with a minor in health from Houston in 2005. He and his wife, Stacey, have two children, Kirby and Macey.
