STATE COLLEGE — Penn State has made big defensive plays lately, most too late to really matter.

Take the last two games for example. The Nittany Lions have created multiple turnovers, forced eight punts, and allowed just 10 points on 13 combined second-half possessions. It would be a winning formula had the first half of those games not gone so badly.

“We see what we’re capable of as a team,” defensive tackle P.J. Mustipher said. “It does give us momentum, but we’ve got to use it. It means nothing if we show what we’re capable of in the second half if we don’t come out in the first half against Iowa.”

If the Nittany Lions start slow again when the Hawkeyes (2-2) visit Beaver Stadium on Saturday, they’ll likely be headed for their first 0-5 start in program history.

It would be an ignominious notation for a team that’s become just the second since 1984 to begin 0-4 after starting the season ranked No. 7. For other reasons, including pride, they’ll look to avoid doing so.

“We know collectively how we can play and what we can do,” linebacker Jesse Luketa said. “Our emphasis and our focus is getting to that point early. When we get our cleats sunk in the grass and we start playing hungry and flock to the ball, 11 being relentless, it’s very hard for offenses to play against us.”

So far, they haven’t been able to flip the momentum as a lumbering offense struggles to find its way. Penn State has been outscored 93-26 in the first half of games and hasn’t led since the first overtime period of their season-opener on Oct. 24.

Halftime adjustments have helped.

This week, the team’s defenders have tried to better prepare themselves to react to unfamiliar offensive looks early in games like Ohio State’s 62-yard handoff to receiver Garrett Wilson that opened a long, grueling night of chasing Buckeyes three weeks ago.

But Penn State’s offense has helped make it easy for the opposition to ring up points against their teammates. It was already going to be tougher when star linebacker Micah Parsons opted out before the season began.

Over the first four games, Penn State has allowed 27 first-half points off turnovers.
