John Lynch said Thursday that the 49ers signed well-traveled free agent Jonathan Cooper this week to compete for one of the team's guard spots.
Which spot? Lynch said that will be sorted out in the offseason, but it's safe to say he and the 49ers are happier about the competition at guard than they were at this point last season. San Francisco surrendered 43 sacks last season -- tied for 10th most in the league -- with most of the pressure coming from the interior. They didn't draft any guards in 2017 and made several additions to the position -- signing Brandon Fusco and Tim Barnes; trading for Laken Tomlinson -- after the draft.
