Isaac Seumalo Bio
Isaac Seumalo, born on October 29, 1993, in Honolulu, Hawaii, is an American professional football guard in the National Football League (NFL). Standing 6 ft 4 in and weighing around 303 lb, Seumalo has built his reputation as a reliable interior lineman known for steady pass protection and smart positional play. He is currently listed as a member of the Arizona Cardinals after spending the 2023 through 2025 seasons with the Pittsburgh Steelers. Across his NFL career, Seumalo has been recognized with a Pro Bowl selection and a Super Bowl championship, both earned through a long climb from overlooked recruit to a cornerstone offensive guard.
Early Life and Background
Isaac Seumalo was born in Honolulu, Hawaii, and is of Samoan descent. During his early childhood, his family relocated to Corvallis, Oregon, where he would grow up and eventually begin his football journey. He first attended Santiam Christian School, where he played football through his freshman and sophomore seasons before transferring to Corvallis High School. At Corvallis, Seumalo quickly stood out on both sides of the ball, earning 5A First-team All-State recognition as an offensive and defensive lineman during both his junior and senior years. Recruiting analysts regarded him as a four-star prospect, and Rivals.com listed him as the No. 3 offensive guard in his recruiting class.
Seumalo chose Oregon State over scholarship offers from Oregon, Stanford, and Southern California, a decision partly shaped by family ties to the program. His father, Joe Seumalo, was a coach on the Oregon State staff, giving Isaac a strong understanding of the Beavers’ system even before he arrived on campus. He spent summers working out on the Oregon State campus, which helped him transition smoothly into the college level as a highly regarded recruit.
Path to American Football
Seumalo’s path to the NFL began in earnest when he enrolled at Oregon State in 2012. Almost immediately, he carved out a significant role on the offensive line, becoming the first true freshman to start at center for the Beavers since Roger Levasa in 1978. He appeared in all 13 games that season and earned Freshman All-American honors from outlets such as College Football News and CBSSports.com, along with honorable mention All-Pac-12 recognition. One early highlight was his strong performance against Utah defensive lineman Star Lotulelei, a reigning Pac-12 Defensive Lineman of the Year.
His second college season showed similar promise, as he started 12 of 13 games, splitting time between center and right tackle, and was named Pac-12 All-Conference second team as well as Pac-12 All-Academic first team. A foot injury suffered at the Hawaii Bowl forced him to redshirt the following year, but he returned to start all 12 games of his redshirt junior season, lining up at right guard and left tackle. After that season, Seumalo announced he would forgo his senior year and enter the NFL Draft, becoming only the sixth Oregon State player to leave school early for the league.
Isaac Seumalo Career
Early Career (2016–2017)
The Philadelphia Eagles selected Isaac Seumalo in the third round, 79th overall, of the 2016 NFL Draft. As a rookie, he saw action in 14 regular-season games, though he was briefly benched in his second season after a difficult performance in a Week 2 loss to the Kansas City Chiefs. Despite that setback, his role on a deep and talented offensive line gave him valuable experience in his first two professional years. The 2017 campaign ended on a high note, as the Eagles defeated the New England Patriots 41–33 in Super Bowl LII, giving Seumalo his first championship ring.
Philadelphia Eagles Breakthrough (2018–2022)
Following the Super Bowl win, Seumalo entered 2018 as a backup left guard before eventually reclaiming the starting role in Week 5. He started nine games before a pectoral injury cut his season short, though he still contributed to a playoff victory over the Chicago Bears. In March 2019, he signed a three-year contract extension with the Eagles, locking in his place as a key piece of the offensive front. He played all 17 regular-season games in 2019 and helped Philadelphia reach the postseason again.
Injuries tested him over the next two seasons, as a knee issue in 2020 and a Lisfranc injury in 2021 cost him significant playing time. He rebounded in 2022 by appearing in all 17 regular-season games and three more in the postseason, helping the Eagles advance to Super Bowl LVII, where they fell 38–35 to the Kansas City Chiefs. After that Super Bowl appearance, Philadelphia chose not to re-sign him, making him a free agent.
Pittsburgh Steelers Era (2023–2025)
On March 18, 2023, Isaac Seumalo signed a three-year, $24 million contract with the Pittsburgh Steelers. In his first season in Pittsburgh, he started all 17 regular-season games, earned a Pro Football Focus overall grade of 71.9, and was ranked 14th among NFL offensive guards. He allowed only 26 pressures and committed just one penalty, then added a postseason appearance in an AFC Wild Card loss to the Buffalo Bills. His steady play quickly made him a trusted starter along the Steelers’ offensive line.
The 2024 season began with a preseason pectoral injury that kept him out of the lineup for the first four weeks. After returning in Week 5, he quickly reasserted himself, taking more than 96 percent of offensive snaps by the team’s Week 9 bye and not surrendering a single sack or quarterback hit. His pass-blocking grade of 74.7 placed him 21st out of 69 eligible guards, and he went on to earn his first career Pro Bowl selection. He continued to anchor Pittsburgh’s front through the 2025 season before his next career move.
Arizona Cardinals Era (2026–Present)
On March 11, 2026, Seumalo signed a three-year, $31.5 million contract with the Arizona Cardinals, beginning a new chapter of his NFL career. He is currently listed as an active member of the Cardinals’ offensive line, wearing No. 73. His veteran presence and track record of durability are expected to play a central role in the Cardinals’ plans along the interior of their offensive front.
Driving Style and Strengths
Seumalo is widely respected for his technique, balance, and football intelligence at the guard position. He is considered strongest in pass protection, where his quick footwork and strong base help him mirror athletic pass rushers, and he has shown the versatility to play center, guard, and tackle across his career. His experience working with multiple offensive systems in Philadelphia and Pittsburgh has also made him an effective communicator and reliable presence in the locker room.
Notable Events and Milestones
Seumalo’s career is highlighted by his Super Bowl LII championship with the Philadelphia Eagles, his appearance in Super Bowl LVII, and his first Pro Bowl selection in 2024 with the Steelers. Earlier, his debut season at Oregon State set a historic standard as he became the first true freshman to start at center for the Beavers in decades.
