Armstrong Nnodim has spent much of his Penn State career learning the ropes. Now healthy again, the third-year defensive tackle is ready to put that education to work when the No. 13 Nittany Lions open Big Ten play Saturday against Wisconsin at Beaver Stadium.
Nnodim, who is listed at 6-2 and 310 pounds, sat out Penn State’s first two games because of an injury before returning in Week 3 against Buffalo. He played 15 snaps and finished with two tackles, then said he feels 100 percent and expects no restrictions against the Badgers.
He’s leaned heavily on the older players around him, especially eighth-year Siale Taupaki and sixth-year Keanu Williams, who share his position and have helped him settle into the defense.
“[They’re] really great mentors,” Nnodim said. “They just bring me along and everything because they’re familiar with this defense.
They're very knowledgeable guys, very fun guys to play with and be around. So it's just been a great thing.”
That guidance has mattered to a player Penn State identified as one of its more overlooked transfer additions. Nnodim came in from Oklahoma State after two seasons there, where he started four games in 2025, totaled 11 tackles and added a sack.
At Penn State, he made an immediate impression. Position coach Ikaika Malloe described him as a “pit bull,” while teammate Cooper Cousins called him an “absolute bruiser” after facing him in spring practice.
Nnodim said his first experience in Beaver Stadium felt “electrifying,” but the bigger takeaway has been the people around him. He said teammates were there for him whenever he was down, and that support helped him keep his focus on the bigger picture.
“It was always somebody in my corner to pick me up, keep my head up, and just remember that we have a bigger goal in front of us,” Nnodim said.
That connection has grown inside a defensive line room built on different backgrounds. Nnodim is from Texas, Taupaki and Williams are from California and Dallas Vakalahi is from Utah, among others. Malloe pushed that group to get “vulnerable” with one another during the offseason, and Nnodim said that openness has strengthened the unit.
“We just understand each other's backgrounds, knowing where everybody came from, and that also fuels us to play for each other harder,” Nnodim said. “We basically just shared our stories, understanding where we’re coming from and why we play football, why we came to Penn State.”
“It's just finding something that we have similarities in, as far as playing games,” Nnodim added. “For instance, y'all know Keanu [Williams]. Keanu is a big Lego-builder, so just interacting with him about that.”
Off the field, Nnodim has become one of the team’s most recognizable personalities. He’s known for singing “Happy Birthday” to players and staff members, and strength coach Reid Kagy called him “the brightest personality in the entire team” this summer.
“Armstrong is probably the brightest personality in the entire team,” Penn State strength coachReid Kagy said this summer. “If you haven't figured it out yet, he’s loud.
He does not mind talking, which is a great thing. Armstrong is a connector.
Armstrong is a glue guy. Armstrong is a guy who brings everybody together on this team.”
On the field, that same energy shows up in the way Penn State’s defensive line plays. Nnodim said the group is operating “unselfishly” and “attacking violently,” and the numbers back that up: Penn State’s run defense has allowed 111 yards per game and two rushing touchdowns.
Even with that success, Nnodim said the group still has work to do.
“There are areas that we need to clean up,” Nnodim said. “When we're really good, we're really good, and we're all for it… So it's just being more consistent.”
Penn State and Wisconsin kick off at 5 p.m. ET Saturday at Beaver Stadium. The game will stream live on Peacock.

Former Penn State Transfer Miss Is Getting A Real Jets Chance
Malik McClains football path has taken another turn, and this one gives the former Penn State wide receiver a real chance to stick in the NFL. After a college career that never fully took off and a disappointing season in Happy Valley in 2023, McClain signed with the New York Jets and worked his way from the practice squad to the 53-man active roster.
For a player whose college production never matched the early promise, this is the kind of opening that can keep a career moving. McClains path now appears to run primarily through special teams, where roster spots are earned by doing the little things well and making himself useful on game day, a role that could finally give him a foothold at the next level.

Penn State Fans Have A New Reason To Dread Wisconsin Week
Penn States Big Ten opener against Wisconsin already had the feel of an early barometer game, and now there is a viewing wrinkle on top of it. The matchup is slated to stream on Peacock, which means fans who want to watch it will need a subscription rather than a standard TV broadcast, adding another layer of inconvenience to a week that already carries plenty of attention in State College.
The timing is notable because Penn State has not exactly been surrounded by marquee television treatment this season, and the first few home crowds have shown some softness for nonconference games, including the Buffalo matchup that drew the smallest attendance at Beaver Stadium since 2019. An NBC broadcast is coming in week six, but before that arrives, Wisconsin week has turned into the kind of date Penn State supporters may already be bracing for. [Read more 🡒]
Penn States First Big Ten Lineup Under Matt Campbell Comes Into Focus
Matt Campbell is sticking with a familiar routine in Happy Valley, declining to release an official weekly depth chart as Penn State moves through the 2026 season. The approach mirrors what the previous coaching staff did, leaving Lions247 to piece together a projected lineup from practice observations and information coming out of the program.
That unofficial chart is expected to stay fluid from week to week, with updates coming as roles and availability change. Under Big Ten rules, player availability designations will still be attached each week, giving fans at least a clearer picture of who is in and who is out even if the full pecking order remains an internal matter.
