Seth Wallace

Seth Wallace was elevated to assistant head football coach at the University of Iowa in January, 2024. He has coached Hawkeye linebackers since 2016 and served as Iowa’s assistant defensive coordinator the past eight seasons.

Wallace was Iowa’s recruiting coordinator in 2014 and 2015, while also coaching cornerbacks and nickelbacks in 2015. He worked with the defensive line in 2014. Wallace previously served as a graduate assistant coach on the Iowa staff for three seasons (2006-08).

Iowa’s defense consistently ranks among the best in the country, ranking in the top 20 in scoring defense each of the last 10 seasons. The Hawkeyes have allowed fewer than 20 points per game the last nine seasons, the longest active streak in the country.

Iowa has held 10 teams without a touchdown since the start of the 2022 season. The unit allowed one touchdown or less in 10 games in 2023 and in 22 of the last 40 contests.

Under Wallace’s leadership, Iowa’s linebacking corps has consistently been one of the nation’s best. Over the past nine years, Wallace has coached five linebackers who have garnered All-America recognition. An Iowa linebacker has led the Big Ten in total tackles three of the last four seasons. Wallace has mentored 11 linebackers to all-conference status and eight players have gone on to play in the National Football League.

The Hawkeyes won 18 games the last two seasons, including 10 and capturing the Big Ten West Division in 2023. Iowa earned berths to the Citrus and Music City bowls after the 2023 and 2024 seasons, respectively, and finished 2023 ranked No. 24 nationally. The Hawkeyes have been ranked in the final AP Top 25 five of the last seven seasons.

Linebacker Jay Higgins tied the school record for most tackles in a season, was a Butkus Award semifinalist, and was honored as a first-team All-American in 2023. He followed up with a unanimous consensus All-America season in 2024, being the only player in the nation with 100+ tackles and four interceptions. Higgins was also tabbed the Butkus-Fitzgerald Big Ten Linebacker of the Year and was a semifinalist for the Lombardi, Lott IMPACT and Butkus awards. Linebacker Nick Jackson was honorable mention all-conference in 2024 and finished his career with the second most tackles in FBS history.

Iowa’s defense led the way in 2022, including posting just the second shutout in Iowa’s 35 bowl games. The defense led the nation in with seven defensive touchdowns, including two interception return scores in the bowl win. The Hawkeyes won eight games, including five of the last six. Iowa’s defense was in the top 12 in the nation in scoring defense (second), total defense (second), pass efficiency defense (fourth), passing yards per game (sixth), first down defense (10th), third down defense (11th) and rushing defense (12th).

Linebacker Jack Campbell earned unanimous consensus All-America honors, while earning the Butkus Award and the William V. Campbell Trophy. He is the first Hawkeye player to win each of the awards. He was the Nagurski-Woodson Big Ten Defensive Player of the Year and Butkus-Fitzgerald Big Ten Linebacker of the Year. Linebacker Seth Benson also earned second-team All-Big Ten accolades.

Campbell was selected in the first round of the 2023 NFL Draft, taken by the Detroit Lions as the 18th player selected. He has been a mainstay on Detroit’s defense the last couple years. Benson signed a free agent contract with Denver immediately following the draft.

Iowa’s streak of 12 straight bowl invitations is the longest in school history and its streak of 12 straight winning seasons ranks fifth best among power conferences. The Hawkeyes have earned 31 conference victories between 2020-24, matching its highest five-year conference win total in program history (1981-85 and 2019-23).

The Hawkeyes won 10 games in 2021, winning the Big Ten West Division title and advancing to the conference championship game. Iowa concluded the season with an appearance in the Citrus Bowl and was ranked 23rd in the final national ranking.

He scored two of Iowa’s four defensive touchdowns in 2021, including a fumble return and an interception return. Benson was second on the team with 105 tackles while earning third-team all-conference honors.

Following back-to-back narrow losses to open the 2020 season, Iowa won its final six games, all in Big Ten play. The Hawkeyes allowed just seven points in three of the six wins. The winning streak included road wins at Minnesota, Penn State and Illinois, and trophy game victories over Minnesota, Nebraska, and Wisconsin. The Hawkeyes were ranked 15th in the nation in the final CFP ranking and Coaches Poll, and 16th by the AP. The Hawkeyes were selected to compete in the 2020 Music City Bowl, but that event was canceled.

Iowa’s defense in 2020 led the nation in yards per play (4.3). The Hawkeyes ranked among the national leaders in several additional categories, including scoring (16.0, 7th), pass efficiency defense (110.1, 9th), rushing defense (107.6, 11th), total defense (313.8, 12th), red zone defense (.727, 12th) and interceptions (11, 19th).

Iowa won 47 games from 2015-19, the highest total in school history over any five-year period, and a total that ranked ninth nationally. Iowa won its final four games in 2019 and ranked 15th in the final Associated Press and coaches polls.

Senior linebacker Nick Niemann led the Hawkeyes in tackles and ranked fourth in the Big Ten in tackles per game (9.6) in 2020.

Niemann was selected by the Los Angeles Chargers in the sixth round of the 2021 NFL Draft, while Barrington Wade signed a free agent contract (Baltimore) immediately following the draft.

The Hawkeyes concluded 2019 with a 10-3 record following a 49-24 rout over No. 22 USC in the Holiday Bowl. The three losses were all to ranked opponents by a combined 14 points. Iowa was 4-1 in trophy games for the third straight season.

The four losses came by a total of 23 points and all were decided in the final minutes of play. Iowa tied for second in the Big Ten West Division.

Iowa’s linebackers were an inexperienced crew in 2018 but contributed greatly to Iowa’s high national ranking in several team categories. Amani Hooker, splitting time between safety and outside linebacker, earned All-America recognition while being named the Tatum-Woodson Big Ten Defensive Back of the Year. Hooker declared for the NFL following his junior season and was selected in the fourth round of the 2019 NFL Draft by Tennessee.

The Hawkeye defense led the nation with 21 interceptions in 2017, led by defensive back Josh Jackson, who led the nation individually with eight interceptions to match Iowa’s single-season record. Jackson and linebacker Josey Jewell each earned unanimous consensus All-America honors. The Hawkeyes ranked 17th in the nation in scoring defense (19.9), allowing less than 20 points per game for the third consecutive season. Iowa matched a school record with four interception return touchdowns.

Jewell led the Big Ten in tackles for the second time in three seasons (he was second as a junior) and ranked fourth in the nation in tackles per game (11.3). He earned unanimous consensus All-America honors and was named the Big Ten Conference linebacker and defensive Player of the Year. Jewell earned the Lott IMPACT Trophy and the Jack Lambert Trophy and was a finalist for the Nagurski Trophy.

Jewell became the third Hawkeye selected in the 2018 NFL Draft when he was selected in the fourth round by the Denver Broncos.
