The playbook for building an elite pass defense, as most people write it, goes: get to the quarterback and take away the deep ball. Houston's 2025 defense did neither particularly well and still finished #1 in the NFL in EPA allowed per pass play.

The Texans allowed -0.217 EPA per pass play in the 2025 regular season, the best mark in the league — clear of #2 Minnesota (-0.148), #3 Cleveland (-0.132), #4 Jacksonville (-0.119) and #5 New England (-0.116). They allowed a completion percentage of 54.1%, third-lowest in the NFL behind only Denver (51.7%) and Philadelphia (52.6%). Their sack rate was 7.5% of dropbacks — respectable, but not a top-tier pass rush; seven defenses got to the quarterback more often.

The interesting part is where the damage came from. It wasn't the deep ball. It was everything in front of it.

The short-throw layer

Split Houston's 2025 pass defense by target depth and one number does almost all the work:

Houston allowed -0.123 EPA/play on short throws, the best mark in the NFL. Philadelphia was 2nd at -0.068, then Jacksonville (-0.014), New England (+0.014) and Minnesota (+0.017). Houston's short-throw number sits in a tier by itself, 0.055 EPA/play clear of second place.

On behind-the-line throws Houston was 5th at -0.345 EPA/play on 126 attempts, behind Indianapolis (-0.597 on 90 attempts), Buffalo (-0.560 on 108), New England (-0.413 on 118) and Minnesota (-0.360 on 83) — all on smaller volumes than Houston faced.

Underneath, in other words, quarterbacks throwing at Houston were bleeding value on almost every attempt.

The deep ball went the wrong way

This is the part that inverts the usual template. Here's Houston's depth-bucket EPA/play allowed in back-to-back seasons:

Deep-ball completion percentage allowed jumped from 20.0% in 2024 to 31.2% in 2025, on 77 attempts. Six deep interceptions in 2025 (matching six the year before at nine attempts more volume) kept the per-play number from being uglier, but the trend is unambiguous: Houston conceded more explosive value through the air on deep shots in 2025 than it did in 2024. The defense didn't get better by taking the top off. It got better by making everything short of it toxic.

Offenses adapted, and it didn't help

You can see quarterbacks trying to solve this in real time. The share of pass attempts against Houston that traveled behind the line of scrimmage climbed from roughly 18.6% of attempts in 2024 to 21.4% in 2025. Short-throw share held about steady, ticking from 46.7% to 47.1%. Intermediate share fell from 20.5% to 19.7%, and deep share fell from 14.9% to 13.1%.

Under normal circumstances, shifting attempts to the safest depth of the field is a sound idea. Against Houston, it just meant more reps at the depth Houston defended best. A couple of secondary indicators tell the same story:

• YAC per completion allowed fell from 6.14 in 2024 to 4.97 in 2025 — nearly 1.2 yards of catch-and-run erased per reception, the kind of drop you'd expect from a defense that was tackling the catch rather than chasing it.
• Passes-defended rate ticked up from about 14.7% of attempts in 2024 to roughly 15.3% in 2025 — 4th-highest in the league, behind only Jacksonville, Philadelphia and Detroit.

Coverage and tackling, not pressure

The pass-rush numbers make the mechanism plain. Houston's sack rate went from about 7.7% of dropbacks in 2024 to 7.5% in 2025 — essentially flat, and outside the top half of the league both years. In 2025, seven defenses recorded a higher sack rate than Houston's, led by Denver (9.8%), Cleveland (9.4%) and Minnesota (9.3%).

Whatever changed for Houston year-over-year, it didn't come from getting more pressure on the quarterback. It showed up in the coverage numbers instead: less yardage after the catch, more passes knocked away, and by far the league's best per-play number on throws in the 0-9 air-yard range — the bread-and-butter of a modern passing offense.

What to take from this

The default mental model of an elite pass defense — get home, cap the deep shot — describes maybe half the league's good units. Houston in 2025 was the other half: a defense that allowed a noticeably higher rate of completions and value on deep throws than the year before, didn't improve its pass rush, and still finished #1 in EPA per pass play because almost nothing underneath worked for the offense.
