NFL Draft Interior Offensive Line Rankings

How the draft market prices interior offensive linemen, what evaluators weight, and every class we cover ranked within the position.

How the market prices the position

Interior line is the market's most reliable discount. Guards and centres are drafted well behind their grades because teams believe the position is fillable later and because the interior is less exposed than the edge. That belief is mostly right, which is why the discount persists. A centre with genuine starting traits is scarcer than a guard and prices slightly higher.

What evaluators actually weight

Play strength and hand placement dominate the evaluation. For centres, the pre-snap responsibility, identifying fronts and setting protections, is as much of the job as blocking, and it is why the position rewards experience over athleticism more than any other line spot.

The recurring failure mode

Interior linemen who win on positioning against smaller college defensive tackles often struggle with NFL nose tackles who can move them backwards. Anchor is the trait that fails to translate most often.

How the interior offensive line groups compare

• 2027: 53 ranked so far, 3 inside the top 32 of the board and 11 inside the top 100. 5 are currently projected into the first round, though the class has not been drafted. Carter Smith leads the group at No. 13 overall.
• 2026: 44 ranked, 1 inside the top 32 of the board and 9 inside the top 100. 29 were drafted, 2 in the first round. Olaivavega Ioane led the group at No. 14 overall.

Read the top-of-board numbers before the counts. Depth at a position is common and cheap; a genuine top-of-the-draft player at one is not. The best interior offensive line we have ranked across these classes sits at No. 13 overall in 2027, against No. 14 in 2026, and that gap explains far more about how the two drafts will be shaped than the difference in how many players each class carries.

Interior Offensive Linemen by draft class

Each class's rankings are a separate page, frozen once that draft is complete.

How to read these rankings

Three numbers appear on the class pages and they answer different questions. Board rank is the prospect's slot on the consensus big board, across every position: it is the closest thing to an objective statement of how good the industry thinks he is. Positional rank is his place within this group alone, written IOL1, IOL2 and so on, which is what matters to a team that has already decided it is drafting a interior offensive line. Projected range is where published mock drafts actually have him going, and it is the only one of the three that prices in positional value.

The gap between the first and the third is the whole subject of this page, and for interior offensive linemen it runs in a consistent direction. A interior offensive line ranked 40th on the board who is projected into the fifties is not being underrated by us: he is being priced down by a market that has decided it can find adequate play here later, and that discount is the single most reliable thing about how interior offensive linemen are drafted. The gap is not a mistake by either party, and reading the two numbers together tells you more than either does alone.
