Is any defense actually “weak against tight ends”?
Verdict — Not a real traitNo. Tight-end yards allowed per target is the least repeatable defensive statistic we have measured. What a defense did to tight ends in the first half of a season tells you essentially nothing about the second half.
It is one of the most cited reasons to start a tight end — the matchup chart says a defense gives up the eighth-most points to the position, so you start yours. The problem is that the ranking barely survives contact with the rest of the same season.
| Defensive characteristic | Split-half r | Reads as |
|---|---|---|
| How often a defense plays man | 0.84 | a stable, deliberate choice |
| How well a line run-blocks | 0.42 | weak but real |
| Overall success rate allowed | 0.32 | weak |
| TE yards per target allowed | 0.02 | a coin flip |
Two different questions hide inside “weak against tight ends,” and only one of them has an answer. Which positions a defense concedes throws to is partly a scheme decision, and scheme decisions persist. How many yards those throws gain depends on the receiver, the quarterback and the bounce of the ball.
So if you use a defensive tendency at all, use target share allowed, not yards allowed. And do not let “good tight-end matchup” be the reason you start someone — it is the single least reproducible claim in this dataset, and one of the most repeated.
How this was measured
Every pass thrown to a tight end from 2018 through 2025, grouped by defense and season, from official play-by-play. Each defense-season is split into odd and even weeks and the halves correlated across defenses. Defense-seasons needed at least 20 tight-end targets in each half. Split-half r = +0.021; corrected for half-length, +0.040.
