The San Francisco 49ers are looking to improve their offensive line this offseason, and ESPN's Matt Bowen believes veteran guard Isaac Seumalo would be an ideal free agent target. Seumalo, a former Philadelphia Eagle and Pittsburgh Steeler, is ranked as one of the top-5 offensive guards in the NFL in both pass protection and run blocking.

Why it matters

Upgrading the interior offensive line is a priority for the 49ers, as they look to solidify the pocket and open up running lanes for their offense. Seumalo's combination of elite pass blocking and run blocking skills would make him a perfect fit for Kyle Shanahan's system.

The details

Seumalo, a 10-year NFL veteran, posted a 97.3% pass block win rate and a 76.9% run block win rate last season, ranking him second and fourth respectively among offensive guards. His ability to excel in both zone and gap run concepts, as well as his pass protection skills, would make him an ideal addition to the 49ers' offensive line.

  • Seumalo is set to become a free agent in the 2026 offseason.

What they’re saying

“Improving the interior of the offensive line is a must for Kyle Shanahan's offense. Seumalo can displace defenders in both zone and gap run concepts, plus he would keep the pocket firm in pass pro for quarterback Brock Purdy.”
