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.

The biggest question facing the Kansas City Chiefs as they resume their quest to become the first team ever to win three consecutive Super Bowls is whether 3 1/2 weeks' rest will result in too much rust.

The Lions and Chiefs are in a tier of their own odds-wise, thanks to their 15-win seasons and accordant first-round byes. But both have nagging concerns that, if you squint hard enough, begin to look a lot like vulnerabilities. Will any of their potential opponents through the postseason be able to capitalize on those vulnerabilities?
