All 32 lines graded on what they actually did, and what that is worth in fantasy points — which turns out to be a different answer for every position.
The eight best lines against the eight worst, within each season so no era drives the number, compared on the fantasy points per game of each team's best player at a position. Averaged across 21 seasons, half-PPR.
| Position | Best 8 lines | Worst 8 lines | Difference | Held up in | What it means |
|---|---|---|---|---|---|
| QB | 17.1 | 13.8 | +3.3 pts/g | 21 of 21 seasons | a real edge — worth drafting for |
| RB | 14.1 | 12 | +2.1 pts/g | 21 of 21 seasons | a real edge — worth drafting for |
| WR | 13 | 11.3 | +1.7 pts/g | 21 of 21 seasons | a small, steady edge |
| TE | 8.1 | 6.6 | +1.5 pts/g | 21 of 21 seasons | a small, steady edge |

Split the grade in two and the positions separate. Pass protection is worth +3.1 points a game to a quarterback, +2.5 to a receiver and +1.7 to a tight end — and it was positive in every one of the 21 seasons studied. Run blocking is worth only +0.9 to a running back, and it is -0.5 for receivers: a team that blocks well for the run runs more, and throws less.
Reading it the other way: choosing between two backs, the line's pass protection tells you more than its run blocking does.
A different question. Above is how many points the best player on a good-line team scores; this is whether a player who has not broken out yet is more likely to, measured on the line he played behind the season before.
Good pass protection is worth +2.5 points a game to the WR1 a team already has — but a receiver who has not broken out yet is less likely to break out there. Both are true. Offenses that protect well tend to already have an established No. 1 taking the targets, and a breakout has to come out of somebody's share. A good line is a fine place to own a receiver and a hard place for a new one to emerge.
Everything above measures a line by what it actually did that season. This runs the identical breakout-odds question against PFF's preseason pass- protection projection instead — so it only knows what was knowable before Week 1. Four seasons only (2021, then 2023–2025; 2022's preseason file isn't available), a much thinner sample than the 21 years above — read it as an early look, not a second confirmation of that study.
| Position | Behind a top-10 projected line | Behind everyone else | Sample |
|---|---|---|---|
| QB | 27.3% | 16% | 11 of 61 — small sample |
| RB | 9.8% | 11.4% | 82 of 257 |
| WR | 6.5% | 6.6% | 153 of 488 |
| TE | 6.5% | 5.8% | 62 of 233 |
Only the quarterback shows real separation on a sample this size — 27.3% behind a top-10 projected line against 16% behind everyone else. Running backs, receivers and tight ends are close to a coin flip here, the opposite of how cleanly they separate in the measured study above. Never blended into that study, into a player's grade, or into any score on this site — shown here for the same reason every other thin-sample number on this site is shown rather than left out.
Everything above is measured. This section is a forecast — useful because it accounts for an offseason the tape cannot, and worth less because nobody has played a snap yet. It does not move any player's breakout grade.

Click a column to sort. Grade 50 = league average. Pass and Run are the two halves; a line can be excellent at one and poor at the other. Every column carries the season it is from — the last one is the only forecast in the table.
