Ten NFL free agents Vikings could target to improve the offensive line

Improvements to the Vikings offensive line will be first attempted when free agency opens March 13. The best typically don't become available, but there are more than a handful of players set to become unrestricted free agents who could intrigue the Vikings.

Nothing may be excluded in the overhaul, where guards Nick Easton and Tom Compton are free agents. Guard Mike Remmers is coming off a down season with an expendable contract. They could be in the market for a tackle or at least tackle depth, having discussed moving left tackle Riley Reiff to the interior.

C Matt Paradis, Broncos

Paradis, 29, is recovering from a fractured fibula in November, but he was one of the NFL's best centers last season before his injury. Gary Kubiak knows him well. Paradis started 35 games in 2015-16 while Kubiak was the Broncos head coach, including all 19 games during Denver's Super Bowl season.

Keep in mind center Pat Elflein was a standout right guard at Ohio State, where he was a two-time All-Big Ten selection before becoming the nation's top center as a senior.

2019 NFL free agents: The current list

G Rodger Saffold, Rams

G Ramon Foster, Steelers

Foster has been a constant at left guard for the Steelers, an offense that has surrendered an average of 21 sacks in each of the past four seasons. Kirk Cousins took 40 sacks last fall and would benefit from having a veteran pass protector like Foster up front. Foster did just turn 33 years old, so he could drop off soon.

G Quinton Spain, Titans

Spain is interesting in that he turns 28 in August and has played well in the NFL, despite his recent struggles in Tennessee. He could be had at the right price for a Vikings offense looking to rebuild its line with new talent. Since going undrafted, Spain has started 50 games as the Titans left guard in four seasons.

G James Carpenter, Jets

G John Miller, Bills

Miller, a former third-round pick, is another player with history under Dennison. That history wasn't all good. Miller was benched after four games at right guard under Dennison's Bills two years ago. But Miller rebounded last fall with a better 15 starts that could make him a potential target. The Louisville product turns 26 in June.

OT Trent Brown, Patriots

Brown, who turns 26 in April, figures to be sought after if the Patriots let him test free agency. He was a draft-day trade from San Francisco to New England, where he started 19 games and won a Super Bowl ring in the final year of his rookie contract. Brown was the 49ers right tackle before the Patriots moved him to protect Tom Brady's blindside.

OT Jordan Mills, Bills

OT Ty Sambrailo, Falcons

Sambrailo, who turns 27 in March, was a second-round pick by Gary Kubiak's Broncos in 2015. His NFL career hasn't ascended after his three-game rookie stint at left tackle ended on injured reserve. He's started two to four games each of the last three seasons, including at right tackle and left guard for the Falcons. Sambrailo played for Colorado State, which is Vikings quarterback coach Klint Kubiak's alma mater. Could be a depth target.

OT Ty Nsekhe, Redskins
