LAS VEGAS — The Ravens opened as substantial favorites over the Steelers in the wild-card round playoffs, a little surprising given postseason point spreads tend be tighter and these AFC North rivals usually play intense games that go down to the final minutes.

The Kansas City Chiefs aren’t just fortunate to have the first-round bye in this year’s NFL playoffs, but they also have another big advantage on the rest of the field. They’re one of two teams to have seven wins against teams currently in the playoffs.
