But on Monday, the Niners made a move to strengthen the offensive line with a veteran National Football League starter who's had success on one of the NFL's best teams. If the Seahawks do not match the offer, Gilliam will join a roster that includes the following offensive linemen.
After Seattle tackle Garry Gilliam visited the San Francisco 49ers and declined a multi-year offer last week, he has now accepted a new one-year deal with the division rival, according to Matt Barrows of The Sacramento Bee.
If nothing else, the pursuit of Gilliam could give the 49ers three offensive tackles with significant starting experience.
Gilliam went undrafted in the 2014 NFL Draft.
The 26-year-old Gilliam started every game at left tackle in 2015 and entered 2016 as the team's starting left tackle.
Gilliam received a tender from the Seahawks in March at the lowest level, meaning Gilliam would get a one-year contact for $1.797 million for 2017 if he makes the team.
Even if Gilliam doesn't earn a starting spot in 2016 with the 49ers, he'll provide quality play and depth on the line, especially if Brown falters or Staley is injured.
And it would have made Gilliam vulnerable to being a salary cap casualty as the regular season nears.
He was then benched late in the season when Bradley Sowell returned from injury and was inserted at right tackle.
Gilliam's time as a starter with the Seahawks appeared to be coming to an end, anyway.
