The San Francisco 49ers face uncertainty at left guard next season with Ben Bartch and Spencer Burford hitting free agency, leaving Connor Colby as the top option. ESPN analyst Matt Bowen suggests Isaac Seumalo would be an ideal addition, noting his impressive 97.3% pass rush win rate and 76.9% run block win rate from his time with the Steelers.
The 10-year veteran, who won a Super Bowl with the Eagles and made the Pro Bowl in 2024, could provide short-term stability while the 49ers develop a long-term solution. Seumalo, who turns 33 during the 2026 season, offers the foot quickness and body control needed to excel in Kyle Shanahan's zone and gap run concepts.
