Most of his numbers are still mostly luck; 50 is average
Grades updated Rechecked every few hours on game days
What we can and cannot say about a lineman. No public data credits one lineman with a block won or lost. This page shows what does exist: how often he is flagged compared with the other linemen, how much he plays, and how his whole line does in the games he starts. The line's numbers are shared by the five who start together, so they describe the unit more than the man.

The read
Isaac has played 5 games for 347 offensive snaps, 5 games started and 1 penalties, but every advanced number is still mostly luck at this point, so his grade of 51 is a placeholder rather than a verdict.
Game to game on line run success: best 59% in Week 3 against SF, worst 24% in Week 5. He beat the typical offensive lineman's line run success in 2 of 5 games.
Season rank climbed: 53rd to 71st percentile since Wk 1.
Lately he is playing worse. Line run success is 39% over the last 2 games (41 runs), against 45% before that. A few plays could easily explain this. Worth watching, not worth believing yet.
When he plays he is on the field for nearly every play.
Too early to call: sacks allowed by his line and penalties per 1,000 snaps. After 5 games the gaps between offensive linemen on those stats are still mostly chance, so we show them without ranking.
Written from his numbers, not from film. 5 games are behind the season figures.

His team
A player is part of a unit. Here is how the Arizona Cardinals do at his job, and who he shares the room with.
Isaac is the Cardinals' 2nd-best offensive lineman by grade (of 4), and the Cardinals' offensive line ranks 16th of 32.
Overall grade, 20 to 80, against all offensive linemen in the league. A teammate with too few plays to grade is listed without one.

Left is the worst at his job, right is the best, and the line down the middle is average. The bubble is his percentile: 90 means better than nine in ten qualifying offensive linemen. Faded bars are still small samples. Outlined bars are stats where, this early, the gaps between players are mostly luck, so they are not ranked yet.

How he has progressed
Where he has ranked among offensive linemen after each week, and every game behind it.
Season rank climbed: 22nd to 64th percentile since Wk 1.
The line is his season-to-date rank among players at his position after each week, from 99 (the best in the league) down to 1 (the worst). It rises when he passes other players, not when he has one big game. Early weeks are noisier because fewer plays are behind them. The shaded weeks are the recent stretch.

Each one against every offensive lineman with at least 150 snaps. Right on the strip is better.

This is his whole line's number: every lineman who starts beside him shares it, so it says how the unit is doing more than how he is.
How often the team's designed runs gain enough to keep the offense on schedule, in the games he started. It is the line, the backs and the scheme together, and the five linemen who start together share it.
The box score: Team rushing yards ignore the down and the distance.
Does it show up in winning? Across 524 games league-wide, teams won 68% of the time when their offensive lineman was in the best third on line run success, and 49% when he was in the worst third.

Sacks as a share of the team's dropbacks in the games he started. It is the line and the quarterback together, and every lineman who starts beside him shares it. Fewer is better.
The box score: No sack is charged to a single lineman in the box score.

Among the 161 offensive linemen we have a grade and a contract for, Isaac Seumalo is 46th on the field and 58th in pay. His grade is still an early read, so this says nothing yet about whether his pay is fair.

Ranks are among the 161 offensive linemen on the teams we track who have both a grade and a contract. A rank near the right of a bar is better play or higher pay.
Contract figures as of 2026-10-12, read from public cap sites (StickToTheModel team cap pages and OverTheCap contracts list and player pages) into a file we keep by hand, for all 32 teams. A deal signed, cut or reworked since may differ, and cap hits are rounded to $0.1M.

The box score
The traditional totals, with where each ranks among offensive linemen. A total rewards volume, which is why the advanced numbers above matter.
Ranks are among players at the same job who have enough plays to be graded. Grades and rankings come from play-by-play, charting and snap-count data, so they cannot see blocking, route running or assignments. See how the grades work.
Data: nflverse play-by-play, CC BY 4.0. Also FTN charting, Pro Football Reference advanced stats, snap counts and injury reports, all through nflverse. Calculations and charts by Raiders Rundown.
