The Arizona Cardinals have a new head coach who is an offensive-minded guy. But in order for an offense to be effective, it must possess a stable, consistent offensive line. Which, the Cardinals don’t have.
On top of players that weren’t getting the job done last year, is the number of offensive line free agents Arizona has this year: OT Jonah Williams and OT Kelvin Beachum. OG Will Hernandez was on that list, but has since been re-signed.

In 2025, the Cardinals’ offensive line was ranked #26. In all fairness, several starters became injured and ended up on IR: LT Valentin Senn, LT Paris Johnson, Hernandez, and Williams.
To make things worse, starting RB James Conner was hurt and ended up IR himself. His backup, RB Trey Bensen, also found IR his new home. Then it was a series of backups and practice squad guys to do their best as starting running backs in the NFL.
The Cardinals need to address getting in some new bodies along the offensive line.
The NFL free agency period begins March 9-11.
So, Arizona needs at least one starter and quality backups for the guard position. Which is frustrating since offensive guard used to be a position of stability. Yes, it’s now a mess.
Here is a free agent guard possibility for the Cardinals: OG Isaac Seumalo.
OG Isaac Seumalo
Pittsburgh Steelers
2025 PFF rating: 73.3
NFL draft: 2016 Round 3, pick #79 (Eagles)
Accolades: Freshman All-American (2012), Second Team All-Pac 12(2013), Pro Bowl (2024), Super Bowl Champion (2017)
2025 season: 14 starts, 769 offensive snaps (92%)
————————————————————————————
Last year, a pectoral injury kept him out of the first four games, but then he excelled, allowing no quarterback hits or sacks all season. Pro Football Focus rated Seumalo 74.7 on pass blocking, and he played on 96.25% of offensive snaps.
This is a guy who has played in 81 NFL games with 60 career starts. He has experience and has played for only two NFL clubs, of which both were continually in the playoffs and had winning programs. That culture could be brought to Tempe by signing Seumalo.
Blessed with a girthy build, he has functional lateral quickness with active feet. His hand strength allows him to punch and lock into opponents.
Seumalo wins with technique rather than relying solely on power. He would make a reliable starter with the ability to handle quick defenders. He is very good in pass sets, although he does lack ideal length and has struggled with more powerful defenders at times.
He has a lot of versatility. He can play both guard spots and center. This would allow a lot of flexibility regarding attrition later in the year. He is efficient at reaching the second level and is a very good pulling specimen.
Seumalo is recognized as one of the league’s most consistent guards and known for his elite technical pass blocking. Did you get the part where he did not allow a single sack this past season?
