2026 NFL Free Agent Rankings: Interior offensive linemen

NFL free agency is a year-round process, as teams scout opposing players to beat them during the season and perhaps sign them in the offseason.

As the 2025–26 NFL season comes to a close, free agency is coming into focus, and teams are beginning to evaluate potential targets to address roster deficiencies. Here are the top interior offensive linemen slated to hit free agency in 2026.

For now, each player’s profile includes three-year snap counts and three-year PFF grades, offering a broader, more stable view of performance than a single-season spike or dip.

1. Tyler Linderbaum, Baltimore Ravens

Snaps: 3,277 | PFF grade: 86.9

Linderbaum ranked as the fifth-highest graded center in the NFL in 2025 and has improved his PFF grade in every season since entering the league, all while heading toward free agency at just 25 years old. While he remains imperfect in pass protection, he has earned PFF pass-blocking grades above 60.0 in three consecutive seasons. He is among the league's best run blockers, however, having posted a PFF run-blocking grade above 80.0 in three of his four NFL seasons.

2. Isaac Seumalo, Pittsburgh Steelers

Snaps: 2,803 | PFF grade: 75

Seumalo has been one of the most consistent offensive linemen over the past four seasons, posting PFF grades between 66.3 and 73.9 during that span. This past season, he ranked seventh among guards in PFF pass-blocking grade (76.4) and 27th in run-blocking grade (67.1).

3. David Edwards, Buffalo Bills

Snaps: 2,550 | PFF grade: 73.7

Edwards logged a career-high 75.0 PFF pass-blocking grade in 2025 and played 1,000-plus snaps for the second year in a row. The 28-year-old was a sturdy left guard for quarterback Josh Allen over the past two years.

4. Alijah Vera-Tucker, New York Jets

Snaps: 1,166 | PFF grade: 79.2

A torn triceps closed the curtains on Vera-Tucker's 2025 campaign before it began — the third season-ending injury of his young career. He has still established himself as a promising guard, earning three straight season-long 70.0-plus PFF overall grades and allowing the fourth-lowest pressure rate (2.8%) among guards in 2024.

5. Joel Bitonio, Cleveland Browns

Snaps: 3,366 | PFF grade: 69.9

The Browns' offensive line struggled this season, but Bitonio was not the reason. The 12-year veteran remained solid in pass protection, allowing just two sacks across 686 pass-blocking snaps and earning a 75.7 PFF pass-blocking grade. While the 34-year-old's future is uncertain, he would still represent a meaningful upgrade to the interior protection of many offensive lines across the league.

6. Kevin Zeitler, Tennessee Titans

Snaps: 3,057 | PFF grade: 81.4

After playing like one of the NFL's top guards in 2024, Zeitler proved to be a shrewd signing for the Titans in 2025. The 35-year-old earned a 74.5 PFF grade, including a 75.4 PFF pass-blocking grade. Having posted an overall PFF grade of at least 71.5 in five consecutive seasons, Zeitler remains one of the league's more reliable right guards.

7. Greg Van Roten, New York Giants

Snaps: 3,297 | PFF grade: 70.8

Van Roten brings versatility to the market, having logged at least 1,750 snaps at both left and right guard along with 306 at center. With the Giants in 2025, the 35-year-old earned a 70.1 PFF pass-blocking grade and posted a pass-blocking efficiency score of 97.7. At this stage of his career, Van Roten profiles as a reliable interior offensive line depth option.

8. Dalton Risner, Cincinnati Bengals

Snaps: 2,123 | PFF grade: 67.3

A regular short-term pickup by teams since leaving the Denver Broncos back in 2022, Risner simply shows up and produces in pass protection. He has yet to have a season where his PFF pass-blocking grade has fallen below 65.0, and his 71.5 PFF pass-blocking grade in 2025 ranked 18th among all guards.

9. Connor McGovern, Buffalo Bills

Snaps: 3,608 | PFF grade: 66.6

McGovern's 69.1 PFF overall grade in 2025 ranked 13th among centers. He has been one of the better interior pass blockers across the NFL and brings some positional versatility, with strong performances at both center and guard in his career so far.

10. Dylan Parham, Las Vegas Raiders

Snaps: 2,767 | PFF grade: 67.8

A four-year starter with the Raiders, Parham might not be a Pro Bowl-caliber player, but he's a capable starter on the offensive line. He's still only 26 years old, so there is some upside. At worst, he's a solid floor player who would improve a weak link on multiple offensive lines around the league.
