The 49ers signed 11 new free agents since the new league year began last week, putting the roster at 67 players. That means new general manager John Lynch and Kyle Shanahan will make 23 additions over the next two months through free agency and the NFL draft to get to the offseason limit of 90.

San Francisco has 10 draft picks, for now, meaning it’s likely to bring in around 13 free agents. Many of those will be undrafted rookies in the days after the draft. But there’s still room for unsigned veterans.

Here are five the 49ers should consider while reshaping the roster.

LB Dont’a Hightower, Patriots

San Francisco hasn’t been linked to Hightower while he considers a return to New England or a partnership with their AFC East rival Jets. But Hightower would be an obvious fit at linebacker on the strong side of the 49ers’ new-look defense. Hightower brings production, versatility and championship experience and is likely the top free agent still available. If San Francisco isn’t in the mix, look for Lynch to address the ‘Sam’ linebacker position early in the draft given its importance patrolling the second level of the defense and being able to rush the passer from the edge.

DT Johnathan Hankins, Giants

San Francisco’s last-ranked run defense should continue to be a point of emphasis. Hankins (6-3, 320) would be a good addition next to Earl Mitchell along the interior of the defensive line after New York allowed the second-fewest yards per run by opponents in 2016. The soon-to-be 25-year-old is a natural 4-3 run-stuffing tackle who could be plugged in right away and significantly improve the team’s depth. For now, it seems Arik Armstead and DeForest Buckner will be used along the edges in base situations and kick inside on passing downs. That could leave a sound rotation of Hankins, Mitchell and Quinton Dial to work along the interior to fill inside running lanes. Dontari Poe might get consideration, but he remains unsigned while teams weigh his history of back injuries.

LB Zach Brown, Bills

Brown, 27, was a Pro Bowler last season after finishing second in the NFL with 149 tackles, including 11 for loss, four sacks and two forced fumbles. San Francisco added Malcolm Smith last week, likely to play on ‘Will’ on the weak side, while Brown could bring sideline-to-sideline speed next to NaVorro Bowman at any of the team’s three linebacker spots. Brown is fast – he ran a 4.50 at the 2012 combine – but also held up well against the run last season. He’s athletic and versatile enough to man the strong side of a defense and cover pass catchers in space. He would likely be a pricey addition, but would instantly become one of the team’s best defenders. He could play ‘Mike’ linebacker if Bowman missed any time after tearing his Achilles in October and would be an option on the weak or strong side in San Francisco’s new 4-3.

WR Michael Floyd, Patriots

Floyd will be an interesting player to watch as the offseason unfolds. He’ll be on house arrest over the next three months, per TMZ, after his DUI in Arizona led to his release from the Cardinals before getting picked up by the Patriots in December. The 27-year-old could likely be had cheaply later this offseason as a buy-low free agent with an intriguing skill set. The former first-round pick had his only 100-yard game of the season against the 49ers in November. The Notre Dame alum averaged 55 receptions, 910 yards and nearly six touchdowns from 2013 to 2015. San Francisco lacks a big, physical downfield threat, which Floyd could provide Shanahan on an inexpensive deal. But that assumes his mind’s in the right place and he’s willing to get on the right track following his legal trouble.

DE Erik Walden, Colts

The 31-year-old pass rusher is coming off a career year with 11 sacks and could be an interesting addition to compete for a job on the edge. The 49ers finished 19th in the NFL with just 33 sacks last season, while 3-4 outside linebackers Eli Harold and Aaron Lynch combined for 4.5. Ahmad Brooks, who will be 33 Tuesday, tied for the team lead with six. Walden’s been durable, missing just three games in his last four seasons with the Colts and could be a cheap rotational pass rusher. San Francisco is likely to add pass rushers in the draft, while Walden could be an affordable option to show young players the ropes, while providing depth and experience.
