Most one-year NFL renaissances are one-sided. The 2017 Rams had Sean McVay's offensive fireworks papering over a still-mediocre defense. The 2013 Chiefs had Andy Reid and Alex Smith cleaning up a broken team by cutting the negative plays. Even the very good turnarounds are usually a story about one side of the ball.

The 2025 New England Patriots are not that. They are the rarest kind of rebuild — a genuine two-way one.

The receipts

New England's 2024 team finished 27th in offensive EPA/play (-0.082) and 29th in defensive EPA/play allowed (+0.070). Both units were bottom-six. They went 4-13 with a -128 point differential.

One year later:

The record followed: 14-3, +170 point differential. That's a 298-point net swing on the scoreboard, and the underlying EPA move — +0.332 total — is the kind of number that almost never shows up on both sides at once.

The historical context

I pulled every one-year team turnaround since 2000 and ranked them by combined offense-plus-defense EPA/play swing. The 2025 Patriots land second all-time — by a rounding error:

The Rams' 2017 leap was almost entirely offense (+0.271 vs. just +0.086 on defense). The 49ers' 2019 rise was mostly defense (+0.186 vs. +0.120). Denver's 2012 was Peyton Manning walking in the door.

Only one team on this leaderboard cleared +0.15 EPA/play on both sides in the same season — and it's the Patriots. I re-checked against every team-season since 2000, and 2025 New England is the only qualifier. Not one other team in the EPA era has pulled off a dual-side 0.15+ jump.

Both units moved, hard, at once.

Drake Maye is doing his part — and then some

The offensive engine has a name. Drake Maye's leap from 2024 to 2025 is one of the largest year-two QB jumps you'll see:

Among qualified 2025 quarterbacks (200+ dropbacks), Maye ranks:

• 3rd in EPA/play (+0.175), behind only Jordan Love (+0.253) and Matthew Stafford (+0.221).
• 1st in CPOE (+8.0). Nobody else in the league is above +6. Baker Mayfield, Brock Purdy, Josh Allen — all behind him. Patrick Mahomes was at +0.34.

A CPOE of +8.0 means Maye is completing passes at a rate 8 percentage points above what an average QB would on the same throws. That's the number that most anchors this as real, not variance — CPOE is throw-quality-adjusted and stabilizes faster than raw yardage totals.

And the defense didn't just come along for the ride

It would be easy to file this as "young QB got better, team got better." That framing misses half the story. Look at what the defense did:

• Defensive EPA/play allowed went from +0.070 (29th) to -0.091 (5th) — a 24-spot leap.
• Pass defense was the driver: from +0.132 EPA/play allowed (worst kind of number) to -0.116. That's a 0.248 swing on the side of the ball where swings are hardest to manufacture.
• Run defense also improved, from -0.001 to -0.055.

For context, the 5th-best pass defense in EPA/play terms in 2025 is elite company — the Patriots finished behind only Houston, Seattle, Minnesota, and Cleveland in defensive EPA/play allowed.

Why this framing matters

The temptation with any 4-13-to-14-3 team is to hunt for the single cause: the coach, the quarterback, the free-agent haul, the schedule. The database says the truth is less clean and more impressive. New England didn't fix one thing. They fixed both things.

The 2017 Rams got the Coach of the Year and the offensive fireworks and are remembered as one of the great modern turnarounds. The 2025 Patriots have a smaller total EPA swing than that Rams team (by 0.025), but they got there by improving both units by a larger amount than any other top-15 turnaround team improved either one. That's a genuinely different — and, historically, rarer — path.

Whether it holds is a separate question. Dual-side improvements this large historically do give some back — regression is real, especially on the CPOE side where +8.0 is an extreme figure. I'd expect Maye's completion-over-expected to drift toward the middle single digits next year, and the defensive number to slide a few ticks as opponents adjust. But the level the Patriots are operating at right now is not fluke territory. Both units are top-five in the league by the most predictive team-strength stat we have.

Since 2000, exactly one NFL team has improved by at least 0.15 EPA/play on both offense and defense in the same year. It's this one.
