Indications are the Vikings want to retain at least half of their own free agents. Here's a look:
Main targets
Terence Newman, CB: King among the Vikings' free agents, he will play a 16th NFL season at age 40.
Marcus Sherels, CB: One of the most consistent NFL punt returners will likely stay in Minnesota via an extension.
Joe Berger, G/C: Turning 36 in May, the linchpin wondered if he'd have suitors. He will, and the Vikings, Giants and Panthers are among them.
Jeremiah Sirles, G/T: The Vikings chose not to use the RFA tender of $1.9 million on Sirles, making him an unrestricted free agent. It's still possible the versatile lineman re-signs in Minnesota.
Shamar Stephen, DT: Stephen has grown into a productive member of the Vikings defensive line rotation and could agree to an extension.
Tom Johnson, DT: Whether Johnson, 33, and the Vikings can agree on a role and price that comes with it could determine if he stays. Mike Zimmer sees Johnson ideally playing a pass-rushing role in 2018.
Nick Easton, G/C: The restricted free agent could get an original-round tender (undrafted) for $1.9 million, or a second-round tender ($2.9 million) if the Vikings are worried about another team making him an offer.
Anthony Harris, S: The Vikings tendered Harris, an exclusive rights free agent, to a one-year contract, keeping the special teams ace in Minnesota.
Mack Brown, RB: The Vikings tendered Brown, an exclusive rights free agent, to a one-year contract. Brown appeared in one game for the Vikings after being released from the Redskins in October.
Kai Forbath, K: Forbath was solid for the Vikings last season, converting 83 percent of his field goal attempts and three of four in the postseason. It wouldn't be a surprise if the Vikings stuck with Forbath moving forward.
On the bubble
Sam Bradford, QB: A "degenerative" knee, as Zimmer called it at the NFL combine, clouds Bradford's playing future. The risk of injury is substantial for someone who has had his left knee surgically repaired three times.
Teddy Bridgewater, QB: Will Bridgewater stay in Minnesota? The Vikings know him best. That said, teams who don't truly know the full scope of his rehab from a dislocated knee and multiple torn ligaments might be more inclined to give Bridgewater a fair shake as a starter.
Case Keenum, QB: Zimmer was openly undecided about Keenum after the season. They passed on the franchise tag. Could Keenum's free-agent market also be too rich for the Vikings? Time will tell.
Jerick McKinnon, RB: McKinnon spoke candidly about the situation in Minnesota (with Dalvin Cook as a fixture) and how he wanted to be more of a featured back. That will likely lead McKinnon out of Minnesota after four seasons.
Emmanuel Lamur, LB: The linebacker played 117 defensive snaps in two seasons after signing a two-year, $5.5M deal. It's not clear if the Vikings got what they were expecting from Lamur, who did contribute on special teams.
Michael Floyd, WR: Floyd didn't do much on an incentive-laden one-year deal, returning from a four-game suspension to catch 10 passes for 78 yards, none in the playoffs. The Vikings will likely move on from Floyd.
Bishop Sankey, RB: The former second-round pick tore his ACL in the preseason opener. Sankey hasn't appeared in an NFL game since the 2015 season.
Tramaine Brock, CB: Brock played just 51 defensive snaps after the Vikings sent a seventh-round pick to Seattle for the cornerback.
Jeff Overbaugh, LS: Overbaugh is unlikely to return after he was signed to replace Kevin McDermott for the season finale and two playoff games. McDermott, coming off a dislocated shoulder, is expected to be ready this summer.
