The 49ers have Pro Bowl players on the left side of their offensive line. They extended their right tackle with a lucrative contract. And their right guard made an ultra-successful transition from offensive tackle.
It's no surprise the 49ers are regarded as one of the top offensive lines in the NFL, including this Rotoworld projection as the No. 2 unit for the 2013 season.
But that does not mean all starting jobs are settled. All indications are that the 49ers expect competition in training camp for one starting job.
Veteran center Jonathan Goodwin, 34, was a Pro Bowl alternate last season. But his job will not just be handed to him again this season.
Goodwin, who is entering the final year of his contract, is scheduled to make $3.7 million in base salary for the upcoming season. He does not have a workout bonus written into his contract and has done all of his offseason training in South Carolina, where he makes his offseason home.
Meanwhile, Daniel Kilgore and Joe Looney have been working out daily at the 49ers' practice facility. Those players are expected to offer stiff competition for Goodwin in training camp.
Kilgore and Looney figure into the 49ers' long-range plans, as the 49ers hope to establish continuity on the offensive line.
Pro Bowl left tackle Joe Staley is signed through 2017. Right tackle Anthony Davis is signed through 2019. Right guard Alex Boone, a Pro Bowl alternate after moving from tackle, is signed for three more years. And the 49ers have opened preliminary talks to extend Pro Bowl left guard Mike Iupati, who is signed through 2014.
