Game Preview: What to Expect

Recent Team Performance

Penn State and Iowa are heading into this game with vastly different momentum. The Nittany Lions kicked off the season with a strong 3–0 start, only to hit a rough patch with three consecutive losses in Big Ten play, leaving them at 0–3. Their recent struggles include an overtime 30–24 loss to Oregon, a high-scoring 42–37 upset by UCLA, and a nail-biting 22–21 loss to Northwestern. Adding to their challenges, Penn State parted ways with head coach James Franklin on October 12, 2025, creating even more uncertainty for the team.

Iowa, on the other hand, is 4–2 overall and 2–1 in Big Ten play, showing signs of resilience. After a 20–15 loss to Indiana, they bounced back with a dominant 37–0 shutout of Wisconsin, previously had a 38–28 victory at Rutgers and a commanding 47–7 win over UMass. Before that, a narrow 16–13 loss at Iowa State, was closely contested. The shutout against Wisconsin, coming right after their bye week, marked a turning point, giving Iowa a clear boost in confidence. These contrasting performances make this matchup all the more intriguing.

Players to Watch

One of the biggest storylines is Penn State’s quarterback situation. Drew Allar, who had been the starter, is sidelined for the remainder of the season due to injury, so Ethan Grunkemeyer, a redshirt freshman, will make his first career start against Iowa.

Iowa’s quarterback, Mark Gronowski, has passed for roughly 700+ yards this season with a handful of touchdowns and interceptions, and he has been dealing with a knee issue that could limit his mobility.

On the ground, Kaytron Allen will be a key asset for Penn State, providing stability in the rushing attack. Meanwhile Iowa’s K. Moulton and other backs are contributing in a run-first offense. Iowa’s defense has shown it can stifle offenses, as evidenced in their shutout performance vs. Wisconsin. Injuries and adjustments to new lineups will also play pivotal roles in how these matchups unfold.

Injury Reports and Roster Changes

Injuries and roster adjustments are pivotal factors in this matchup. Drew Allar will be replaced at QB by Ethan Grunkemeyer. Penn State is navigating a major transition after head coach James Franklin was fired on October 12, leaving the team under interim leadership during a critical stretch of the season. For Iowa, the spotlight remains on quarterback M. Gronowski’s knee injury. Although he played through it in the Wisconsin game, any limitations against Penn State’s aggressive pass rush could spell trouble.

Iowa has an additional advantage with a bye week that allowed them to recover and make key adjustments. This extra preparation time comes as Penn State deals with internal turbulence and a compressed timeline to prepare. Adding to the challenge for Penn State, their last win at Kinnick Stadium was back in 2019, making this road game an uphill battle in an already hostile environment.

Team Breakdown: Penn State vs. Iowa

Penn State Nittany Lions Analysis

Penn State is entering this game amid major transitions. With Drew Allar out for the season, Ethan Grunkemeyer will be thrust into his first start in an extremely challenging road environment — a baptism by fire.

The offense has shown occasional explosiveness, but consistency, particularly in the passing game, has been elusive all season.

Expect a more conservative game plan leaning heavily on Kaytron Allen and the rushing attack to ease pressure on the young quarterback. Iowa’s defensive front is disciplined and will push to collapse the pocket, so Penn State’s offensive line must deliver stronger protection.

On defense, the Nittany Lions have had mixed results. While their secondary has had flashes of competence, the unit has been tested often this year and lacks elite consistency. Linebacker Abdul Carter will be central to slowing Iowa’s ground threats, but tackling efficiency and gap discipline — areas the team has struggled with — will be under the spotlight.

In special teams, Penn State leans on reliability. Kicker Alex Felkins has been solid from distance, and field position battles will matter in what's likely to be a tightly contested, low-scoring affair. But with a new head coach (interim Terry Smith) and a freshman under center, maintaining composure and managing game tempo will be true tests for the Nittany Lions.

Iowa Hawkeyes Analysis

Iowa comes into this matchup at 4–2, sticking with the formula that has long defined its program: defense, control of field position, and physicality. Offensively, the Hawkeyes tend to favor a ground-first approach, using the run game to set tempo and reduce exposure to mistakes. Gronowski must maintain efficiency and manage the game.

Defensively, Iowa is among the more disciplined units in the Big Ten. Their front seven has held firm against many rushing attacks, while the secondary has forced some turnovers and disrupted timing routes. In red-zone situations, Iowa has been effective at limiting opponents to field goals, though they are not impenetrable.

Special teams remain a significant advantage. Iowa’s punting unit consistently flips field position, and kicker Drew Stevens is dependable inside shorter ranges. In close games, these small edges often tilt outcomes.

Lastly, the environment matters. Kinnick Stadium under night conditions is one of the more difficult road venues in the Big Ten. Noise, pressure, and crowd energy can disrupt visiting offenses, especially with a first-time starting quarterback. Iowa’s experience in these conditions gives them a valuable edge.
