Ravens at Vikings: Vikings will beat the Ravens if ...

The Ravens have six takeaways in three road games, and their best chance to get a third road victory is to create a couple of turnovers on Sunday. Short of that, the Vikings should handle an inconsistent Baltimore offense and get to 5-2.

Prediction: Vikings 27, Ravens 17.

Three big story lines

Acquaintances renewed

Mike Zimmer faced Ravens QB Joe Flacco 12 times as Bengals defensive coordinator, going 5-7 in those games from 2008-13. Flacco has thrown only four touchdown passes this season against eight INTs.

Wallace returns

The Ravens' leading receiver should be plenty familiar to Vikings fans: Mike Wallace, who came to the team as a possible deep threat but was let go after the 2015 season. He has 239 yards on 15 catches for the Ravens this year, after surpassing 1,000 yards with them last year.

Case Keenum will make his fifth start of the season and will again be without Stefon Diggs as the Vikings face a Ravens D that's generated the second-most turnovers in the league (14) this season. Keenum threw an INT against the Packers and had a couple more passes that could've been picked.

Two key matchups

Vikings QB case Keenum vs. Ravens S Eric Weddle

Weddle went to his fourth Pro Bowl last year and is tied for the team lead with a pair of interceptions. He'll look to disguise coverages as the Ravens secondary attempts to lay traps for Keenum.

Vikings offensive line vs. Ravens LB Terrell Suggs

The Vikings will win if…

• They can avoid the turnovers the Ravens have been so adept at creating this season, and bottle up big plays, either from Baltimore's special teams or its attempts to throw downfield.
