The Opening Drive: Growth Through the Fire
The Numbers Raise Questions. The Tape Provides Answers.
When evaluating a player like Jermaine Mathews Jr., it’s easy to start with the numbers. In today’s game, metrics like PFF grades, completion percentages, and coverage data are readily available — and they can provide value.
But they don’t always tell the full story.
Especially at the cornerback position.
The reality is this: corners live in a world where they are constantly isolated, constantly tested, and often asked to execute within the structure of the defense rather than for the sake of individual production. A missed leverage call, a late rotation, or a scheme-specific responsibility can show up as a negative grade — even when the player is doing exactly what he’s coached to do.
That’s why context matters.
In this Opening Drive, we’re going to evaluate both — what the numbers say and what the tape shows.
Because Mathews wasn’t a rotational piece in 2025 — he was a starter who logged 695 snaps, aligned predominantly as a wide corner (413 snaps) while also seeing meaningful time in the slot (185 snaps), and was targeted 44 times throughout the season. When you play that much at corner, there are going to be ups and downs. That’s part of the position.
His overall PFF defense grade of 62.2 tells one version of the story. His coverage grade of 63.1, a 63.6% reception rate allowed, and 281 yards surrendered on those 44 targets tell another. The 10.0 yards per reception and 99 yards after the catch are areas that deserve attention on film.
But context demands acknowledgment of the trajectory. In 2023, Mathews graded out at an elite 85.9. In 2024, that number dropped to 70.0. In 2025, it settled at 62.2 — a three-year regression that raises legitimate questions, but also one that was happening while he absorbed a significant workload at a program competing for a national championship.
That volume is not nothing.
And development at that level — even imperfect development — carries value.
For this defense to reach its full potential in 2026, the expectation shifts. The Buckeyes don’t need him to just hold up — they need him to impact the game at a higher level, similar to what we’ve seen from players like Denzel Burke and Davison Igbinosun in recent years.
That means:
Eliminating explosives
Winning key matchups on the perimeter
Turning tight coverage into takeaways
His best individual game grade of the season came against Texas (78.0), with strong outings against Purdue (72.0) and Penn State (66.9) mixed in. The floor — a 36.5 against Rutgers — is the kind of tape that keeps coaches and analysts up at night.
That’s the next step.
That’s where the film comes in.
Because when you turn the tape on, you start to see the traits, the competitiveness, and the growth that numbers alone can’t capture.
Clip 1 — @ Purdue | Man Coverage Discipline
Patricia’s defense generally lines up in some form of Cover 1 or Cover 3 with a single high safety and that structural identity is what makes corners like Mathews so important to how this unit functions. Patricia ran a high rate of single high coverages in 2025, deploying Cover 1 and Cover 3 to allow Caleb Downs to slide into the box and affect the run game which means the corners on the perimeter are often on an island, without help over the top. That context matters when evaluating what you’re about to see.
This clip against Purdue is, in my opinion, one of the cleaner reps Mathews played all season — and it’s a direct product of that schematic reality. When you’re a corner playing off the back end of a Cover 3 or dropped into a Cover 1 Rat look, the instinct to reach or grab when a receiver gains outside leverage is real. Mathews doesn’t do that here.
Watch his eyes.
The Purdue receiver works outside leverage on him, trying to create separation on the boundary. Mathews never panics. He never stabs. He tracks the near hip — exactly what you coach — and continues closing space with discipline through the rep. No false steps. No reach. Just patient, controlled technique.
That’s the type of rep that doesn’t always show up in a 63.1 coverage grade, but it’s exactly the kind of football that tells you the foundation is there. Patricia’s scheme asks these defensive backs to shift between man, zone, and match coverage while keeping the quarterback guessing and winning those individual battles in man coverage, even when they don’t result in a pass breakup, is what keeps a defense like this from getting exposed.

Clip 2 — vs. Penn State | Slot Versatility & Recovery
Mathews logged 185 of his 695 snaps in the slot in 2025 — a number that speaks directly to his value beyond just the boundary corner role. That versatility isn’t accidental. It’s a reflection of both his skillset and his mentality. By all accounts, Mathews has been vocal about his willingness to do whatever the defense needs — and that attitude is exactly what makes a player like him useful in a scheme as multifaceted as Patricia’s.
How that shakes out in 2026 will be one of the more interesting storylines of spring ball. With the transfer additions now in the mix at corner, Mathews may find himself kicking inside more frequently than he did last year — or the competition may push him back to his natural home on the boundary. Either way, the ability to play both spots at a high level is a real asset.
This clip against Penn State puts that versatility on display.
The Buckeyes are again in a Cover 1 Rat look here, with Lorenzo Styles as the underneath rat player — sitting in the throwing lane, reading the quarterback’s eyes, and taking away the quick game. That structure gives Mathews a clear assignment: maintain outside leverage through the route with Styles providing the inside bracket underneath.
At the top of the route is where it gets interesting. That’s the moment Mathews loses his outside leverage — not on the release, but at the break point, when the receiver works back to the outside and Jermaine finds himself slightly out of position. That’s the rep. But again, watch the response.
He doesn’t panic. He doesn’t lunge. He gets back to the hip, reasserts his position, and puts himself back in the play. Given that the scheme is asking him to maintain outside with inside help — and he momentarily loses that leverage at the top — the recovery is the story here. He understands his responsibility within the structure, corrects in real time, and finishes the rep competitively.
Clip 3 — vs. Texas | Zone Recognition & Pattern Match
This rep against Texas — his best-graded game of the season at 78.0 — is a masterclass in zone coverage processing. And it’s a different kind of rep than what we’ve seen in the first two clips. Where those showcased Mathews’ man coverage discipline and recovery ability, this one shows something equally important: his ability to read routes and react within the structure of Cover 3.
The Buckeyes are in Cover 3 here. Mathews has a defined zone, and the play design is working against him — or at least trying to. The offense is using a curl route underneath to hold him, with the intent of getting him to commit to that first threat and open up the deeper crossing route coming over the top behind him.
Mathews doesn’t bite.
Watch his eyes through the progression. He’s patient with the curl — he sees it, he respects it — but he never fully breaks down on it. The moment he recognizes the deeper over route developing behind the curl, he disengages and sinks underneath it, getting himself in position to contest what is a much more dangerous throw.
That’s pattern matching. That’s a corner who isn’t just running his landmark and playing his spot — he’s actually processing route combinations in real time and prioritizing threats accordingly. In Cover 3, that’s the entire job. Your landmark gets you in the right area, but your eyes and your processing ability determine whether you’re actually useful when the ball comes out.
For a player whose overall grade dipped to 62.2 in 2025, this rep is an important data point. The tools are there. The processing is there. The Texas game — his best individual performance of the season — showed what Mathews looks like when it’s all clicking together.
The 2026 challenge is making that the standard, not the ceiling.
