Matt Campbell didn’t waste time putting his stamp on Penn State football. Within days of being introduced as the program’s new head coach, Campbell made his first defining staff decision: Defensive coordinator Jim Knowles will not be retained. The message was immediate and unmistakable — the reset is real, and it’s moving with purpose.

Penn State officially welcomed Campbell on Monday, closing a 54-day coaching search that drifted from ambitious to uncomfortable before finally landing on what feels like a stabilizing choice. Campbell, who spent nearly a decade rebuilding Iowa State into a consistent Big 12 contender, made it clear he wasn’t chasing the job. But he also didn’t pretend this opportunity was ordinary. “You knew their excellence and what they stood for — a blue blood football program. No question,” Campbell said during his introductory press conference. “The sacrifice, the passion, of so many of you… I know this — it’s my responsibility to each and every one of you, every single step of the way.”

Campbell’s track record speaks to his patient, culture-first approach

That word — responsibility — has followed Campbell throughout his career, and at Iowa State, it translated into structure, patience, and culture-first decisions that outperformed the program’s resources. He went 72–55 with the Cyclones, won three Big 12 Coach of the Year awards, and turned a historically fragile program into one that expected to compete late every season. Penn State, with its budget, recruiting footprint, and championship expectations, is a different assignment entirely. Campbell understands that, and he’s coaching accordingly.

His first move wasn’t tearing everything down. It was choosing what to keep. Campbell made a point to retain Terry Smith, the interim head coach who steadied Penn State after James Franklin’s firing and kept the locker room from splintering during the season’s final stretch. Smith will remain on staff and coach the bowl game, serving as both a stabilizer and a bridge between eras. “It was critically important for me to keep Terry,” Campbell said. “Building a staff is so critical because you need to build it around the same character values as who you are and what you want your team to stand for.”

That quote matters because Campbell isn’t collecting résumés — he’s aligning people with a vision. Which brings us to Knowles.

Knowles’ departure isn’t personal, it’s philosophical

According to Pete Nakos of On3, Penn State will move on from the veteran defensive coordinator, despite his respected résumé and recent stops at Oklahoma State and Ohio State. Knowles’ departure isn’t an indictment of his coaching ability — it’s a philosophical decision. Campbell is building a staff that reflects how he wants Penn State to operate, recruit, and develop, and that means installing his own defensive identity from the ground up. Knowles will land on his feet because coaches with his track record always do. But at Penn State, this wasn’t about continuity for continuity’s sake. It was about ownership.

Campbell didn’t arrive in Happy Valley to manage someone else’s vision or preserve the remnants of Franklin’s structure. He came to establish his own identity, and he’s moving with clarity. The first hire he kept told players what values still matter. The first coach he let go told everyone else what’s coming next.

What it means for Penn State

The rebuild isn’t loud yet, but it’s deliberate and already underway. Campbell’s approach won’t mirror Franklin’s CEO-style leadership or reliance on star coordinators to carry the program’s identity. Instead, it will reflect the Iowa State blueprint — grounded in culture, consistency, and alignment from top to bottom. For Penn State fans hoping for a quick turnaround, Campbell’s methodical approach might test patience. But for a program that just endured a mid-season collapse and a two-month coaching search, deliberate might be exactly what’s needed.

The next phase of Penn State football starts now, and Matt Campbell is already defining what it will look like — one decisive move at a time.
