The Iowa defense has had its ups and downs this season, but have shown flashes of brilliance all year.
The defensive line underwent a major overhaul this offseason after losing all four starters from last season, and while it's had some growing pains, it's also shown some encouraging signs. The Hawkeyes have been strong against the run, holding opponents to under 90 rushing yards per game, and that starts up front. The defensive line has struggled at times this season, but Bryce Hawthorne has become a critical part of the unit's success.
Phil Parker praised Bryce Hawthorne's work ethic and leadership
The defensive line unit had zero returning starters, but is talented. Early-season results have been mixed, but Hawthorne has led the way. After transferring from South Dakota State, Hawthorne was primarily a reserve, but earned a starting spot this season. Hawthorne waited his turn behind a veteran defensive line over the past few seasons and is making the most of his opportunity. Hawthorne has racked up 19 total tackles and 2.5 sacks in six games, but Phil Parker praised him for his intangibles.
Iowa held its coordinators' interviews during the bye week, and Parker had nothing but praise for veteran DL Bryce Hawthorne. Parker said he's been impressed with how Hawthorne has improved, especially in his leadership. Parker recalled a specific effort play on the sideline when the defense missed a tackle, and Hawthorne chased someone down to stop him. Parker raved about his hustle and how he goes at full speed at all times. Players respect him because he works so hard, and they notice that.
Hawthorne has softened the blow of losing four veteran starters, and he has been heavily involved this season. You never know what can happen when you replace starters, but Hawthorne has worked hard to become a leader and a go-to playmaker up front. Iowa has struggled at times this season to pressure the quarterback, but Hawthorne hasn't had those same issues. He is tied for second on the team in sacks (2.5) and brings veteran leadership that can't be taught.
Iowa will need Hawthorne's production and leadership to help a young defensive front

All of Iowa's aspirations are still within reach with six remaining games, and a trip to the College Football Playoff isn't off the table. Iowa's defense will play a key role in making that happen as the offense still searches for consistency. We still don't know who will start against Minnesota and beyond, but the defense can ease a lot of that pressure by doing what it does best. Iowa's run defense has been elite this season, forcing opponents to abandon the run, but they have been vulnerable against the pass.
Iowa's defense is at its best when the front four regularly pressure the quarterback, and that has been a struggle this season. Parker has used more blitzes and sent more pressure from the linebackers early this year, limiting their effectiveness in the passing game. Michigan, Ohio State, and Washington proved you can beat Iowa with a quick, decisive passing attack, and getting more pressure on the quarterback would go a long way.
Hawthorne has been Iowa's best interior defensive lineman this season, and the program will lean on him in the second half to help limit big plays in the passing game.
