NFL teams must identify and collect as many microscopic edges as they can find, and the coaches of the Lions and Commanders provide one blueprint.

The Baltimore Ravens won easily in the Wild Card game, but there was an obvious dependence on a play that John Harbaugh pointed out as part of the style the team will use for the playoffs.

Here’s a headline our Prince Grimes wrote a week ago: “Dan Campbell inadvertently gave the Rams playoff bulletin board material for the Vikings (and Lions).” WHAT’S NEXT FOR THE VIKINGS?

Though the Ravens have their sights set on a Super Bowl, it’s clear that their long-tenured coach has done enough to earn job security through the Lamar Jackson era.

Last season, Campbell led the Lions to a 12-5 record and their first division title in 30 years, yet he finished third in coach of the year voting, well behind top two, Cleveland’s Kevin Stefanski and Houston’s DeMeco Ryans.

You just know a few of these playoff games will come down to crucial fourth-down decisions. Who will make the right call in crunch time?

One of the Bears ’ longest-standing traditions, right up there with the script B on the head coach’s hat and singing, “Bear Down, Chicago Bears” after scoring, is watching the playoffs on TV. If they’re home to be home on the couch, they might as well try to learn something.
