DBs Play More Than Anyone. QBs Are Throwing at Them Less — and Winning More When They Do.

The quick answer

The top 64 defensive backs play more of the game than any position measured in this series — 93–96% of defensive snaps across 2023–2025, ahead of even linebacker's 86–90%, and durability hit a series-high 92.2% playing 15+ games in 2025. Their production is drifting against them, though. Interceptions per game fell from a 0.183 era average in 2015–18 to 0.155 in 2023–25, and passes defended dropped from 0.707 to 0.612 over the same stretch. At the same time, quarterbacks are targeting the best coverage players less often — median targets per season for this group fell from 69.0 in 2023 to 58.0 in 2025 — while doing more damage on the throws that do go their way, with passer rating allowed climbing from 82.5 to 91.8 across those same three seasons.

What actually moved, and what didn't

We looked at every starting defensive back season from 2015 through 2025 — corners and safeties together, ranked by coverage production (picks first, then pass breakups and tackles) so box safeties don't crowd out the corners who actually drive IDP coverage value. About two per team. Three eras:

Raw stats, not fantasy points. Per-game rates keep 16-game and 17-game seasons comparable. Snap and target numbers only go back three years (2023–2025).

Tackles are up across every era, the same direction found at linebacker. The two coverage-playmaking numbers — interceptions and pass-defended — both moved the opposite way, falling steadily from 2015–18 through 2023–25. More tackles and fewer picks or pass breakups together suggest defensive backs are rallying to more short, quick completions rather than contesting the ball in the air as often. Quicker passing schemes would look like this. So would a thinner group of ball-hawks. The data can't pick one cause. Both numbers still point the same way.

That mix also moves IDP scoring. Most leagues pay 5 for a pick, 1.5 for a breakup, 1.5 for a solo, and 0.75 for an assist — the NextDyne Engine split too. Extra tackles over the decade do not fully cover the missing picks and breakups. Combined tackles went up. Coverage fantasy points went down.

The QBs are picking their spots

The clearest three-year story is what happens when one of these DBs actually gets targeted. Median targets against this group fell from 69.0 a season in 2023 to 58.0 in 2025 — quarterbacks are throwing at the league's best coverage players less often. When they do, they're doing better: passer rating allowed climbed from 82.5 to 91.8. Completion percentage allowed is essentially flat (63.1% to 63.6%). The damage is yards per completion, up from 11.6 to 12.6, and how deep the throw is when it comes, which crept from 9.7 to 10.4 yards.

Put together, that is a QB habit more than a talent story: avoid the top coverage defenders when you can, and when you do throw their way, make it a deeper, more selective shot. Three seasons is a short sample — don't treat it as a locked-in leaguewide plan. Fewer targets and a higher passer rating allowed moving together is still a real pattern, not two numbers wandering around.

The same tackle shift found at linebacker, from a lower floor

The linebacker piece showed assisted tackles going from about a third of the total to nearly half. Same pattern here, from a much lower starting point.

Assisted share for top-64 defensive backs went from about a fifth of tackles in 2015 to nearly two-fifths in 2025 — 21.5% to 38.3%, close to a double — the identical direction found at linebacker, just starting lower — DBs make more of their tackles in open space, after the ball carrier has already gotten through the front seven. Two position groups moving the same way across the same years is harder to dismiss as a quirk of one role. This looks like how tackles get made around the league now.

What this means for the sack question — and what it doesn't

The last two pieces left an open question: 2025 league sacks sit about 6% above 2020, but the top 64 on the defensive line and at linebacker both went right back to their 2020 sack rates. The extra sacks are coming from somewhere those two groups' top players don't explain. DB blitzes were the obvious next guess.

They aren't the answer. This ranking is about coverage, not sacks — a sack is a rare extra at this position, not the job. Looking at every sack in the league, not just the top 64, DB's share barely moved (about 7.4% of sacks in 2015–19, 7.8% in 2023–25). Linebackers as a whole — including edge OLBs, and not just the top 64 — produced 22% more sacks over that stretch. The extra sacks look like they came from the rest of the linebacker group, not from defensive backs.

Draft capital is the weakest signal of any position in this series

2015–2022 classes. A 4-interception season is the DB bar — a low-frequency play, so treat the percentages as a shape, not a talent grade.

Every other position studied so far has a meaningful gap between at least two rounds. Defensive back doesn't. Round 1 and Round 2 picks hit a 4+ interception season at almost the identical rate — 27.7% versus 27.3% — and even Round 3 trails by only 7 points. Interceptions are a low-frequency, high-variance play; a talented corner can go a full season with one or two picks purely because the ball didn't come his way, and a lesser one can get lucky with four. That variance flattens the whole draft-capital curve. Where a defensive back was picked barely moves the odds of a big interception season.

What this means if you're building an IDP dynasty roster

Treat playing time for these DBs as close to guaranteed, which makes health and how often they get targeted the real variables. With snap share this high and durability at a series high, a strong or weak DB season comes down to how often a player is thrown at and how well he performs on those looks — not whether he's on the field.

Don't assume falling interception totals mean a defensive back has lost a step. Interceptions and pass breakups have drifted down for the whole position across a decade. Compare a DB to today's average, not to 2015, before deciding he's slipped.

Watch how often he gets targeted.Fewer looks in a shrinking pool isn't automatically worse play — quarterbacks look like they're avoiding the best coverage players. A low target count next to a strong passer-rating-allowed number can be respect, not decline.

Don't price a rookie DB primarily off draft slot. Interceptions barely separate by round — a second-round corner has essentially the same odds of a four-pick season as a first-rounder. Weigh scheme fit, how often he gets targeted, and coverage role over where he was drafted.
