When you think of Big Ten juggernauts, your mind probably goes straight to the "Big Two" or maybe the recent expansion west. But honestly, if you aren't paying attention to Penn State vs Illinois, you’re missing the weirdest, most grit-to-the-grindstone football and basketball in the conference.
It's a matchup that basically defies logic. One year you have a defensive slugfest that looks like it belongs in 1942, and the next, someone is dropping 90 points on a Tuesday night in February.
The Night Nine Overtimes Broke Football
We have to talk about 2021. If you were at Beaver Stadium on October 23, 2021, you witnessed something that will probably never happen again—mostly because the NCAA changed the rules so it physically can't.
Illinois came into Happy Valley as massive underdogs. They left with a 20-18 win after nine overtimes. Yes, nine. It was the longest game in college football history.
Basically, both offenses just... stopped. It turned into a repetitive cycle of failed two-point conversions that felt more like a glitch in a video game than a high-stakes Big Ten clash. James Franklin’s Nittany Lions were ranked No. 7 at the time. Bret Bielema, in his first year with the Illini, managed to pull off a heist that essentially derailed Penn State's season.
Chase Brown was the absolute engine for Illinois that day, racking up 223 rushing yards. On the other side, Sean Clifford was clearly playing through some serious pain, and the Penn State offense looked totally out of sync. It was ugly. It was beautiful. It was Penn State vs Illinois in a nutshell.

Why 2024 Changed the Narrative
Fast forward to September 28, 2024. This was a different beast. Illinois arrived at Beaver Stadium ranked No. 19, sporting a perfect 4-0 record and looking to prove that 2021 wasn't a fluke.
Penn State, ranked No. 9, wasn't having it.
The atmosphere was electric—over 109,000 fans packed the stands for a night game. Illinois actually struck first with an 11-play drive that ended in a Luke Altmyer touchdown pass to Carson Goda. For a second, the Happy Valley crowd got real quiet. Memories of the 9OT disaster definitely started creeping back in.
But then the Nittany Lions' defense decided to close the door. They held Illinois to just 34 rushing yards for the rest of the game. That’s not a typo. Thirty-four.
- Final Score: Penn State 21, Illinois 7
- Key Performers: Kaytron Allen (102 yards) and Nicholas Singleton (94 yards)
- The Difference: Abdul Carter. He was everywhere, recording 1.5 sacks and forcing a fumble that basically killed any chance of an Illini comeback.
Drew Allar wasn't flashy—135 yards through the air—but he didn't need to be. He just had to be efficient while the "Law Firm" of Allen and Singleton pounded the rock.
It's Not Just a Football Thing
If you think the drama is limited to the turf, you haven't been watching the hardwood. The basketball series between these two has become a total coin flip lately.
Just this month, on January 3, 2026, Illinois went into The Palestra in Philadelphia—the "Cathedral of College Basketball"—and took down Penn State 73-65.
The Illini are currently ranked No. 20, and they played like it. Senior Kylan Boswell dropped 18 points, but the real story was the freshman, David Mirkovic. He’s a beast. He finished with a double-double (13 points, 10 boards) and looked like a future NBA lottery pick.
Penn State’s Kayden Mingo tried to keep them in it with 16 points and some lockdown defense, but the Nittany Lions just couldn't overcome a cold shooting night. They went 0-3 in the Big Ten to start the year. Honestly, Mike Rhoades has his work cut out for him if they want to make a run in March.
The "Paterno 409" Factor
For the history buffs, you can't mention Penn State vs Illinois without talking about 2011. It was a miserable, rainy day in State College. Penn State won 10-7.
Why does it matter? It was Joe Paterno’s 409th win.

At the time, it made him the winningest coach in Division I history, passing Eddie Robinson. It was a sloppy game where Matt McGloin had to grit out a win while clearly injured. Little did anyone know, it would be the final victory of Paterno’s career. The series has always had this weird way of being the backdrop for massive, program-defining moments.
Looking Ahead: What to Watch For
So, what’s next for Penn State vs Illinois?
If you're betting on these games or just a die-hard fan, keep an eye on the trenches. Whether it's the football line of scrimmage or the battle for rebounds in the paint, the team that wins the "physicality" battle usually wins the game.
Illinois is currently in a golden era under Brad Underwood in basketball, but football is still trying to find that consistent top-tier status. Penn State is trying to break through that "Elite but not quite Champion" ceiling.
Actionable Insights for Fans:
- Watch the Recruiting Trail: Both schools are fighting over the same four-star recruits in the Midwest and Mid-Atlantic. Whoever wins the battle for New Jersey and Eastern PA usually has the edge.
- Home Field Matters (Until it Doesn't): Illinois has shown they aren't afraid of the White Out or the Palestra. Don't assume Penn State has an easy "W" just because they’re at home.
- The "Under" is Your Friend: Historically, football matchups between these two tend to stay low-scoring. Both programs pride themselves on "hard-nosed" defense.
Check the upcoming schedules for the 2026-2027 season. With the Big Ten expanding, these traditional matchups are becoming even more precious. Don't miss the next one.
