Every week for the duration of the 2025 regular season, USA TODAY Sports will provide timely updates to the NFL's ever-evolving playoff picture – typically starting Sunday afternoon and then moving forward for the remainder of the week (through Monday's and Thursday's games or Saturday's, if applicable. And, when the holidays roll around, we'll be watching then, too).

What just happened? What does it mean? What are the pertinent factors (and, perhaps, tiebreakers) prominently in play as each conference's seven-team bracket begins to crystallize? All will be explained and analyzed up to the point when the postseason field is finalized Sunday, Jan. 4.

Here's where things stand with Week 18 underway:

x − 1. Seattle Seahawks (13-3), NFC West leaders: Win at Silicon Valley in Week 18, and they secure the division and NFC's top seed. Remaining schedule: at 49ers

y − 2. Chicago Bears (11-5), NFC North champions: Green Bay's loss in Week 17 was doubly sweet, as it also wrapped up the division title for Da Bears. However coming up short in last Sunday's thriller at San Francisco means Chicago can't get home-field advantage ... though the Bears could see the Pack in the wild-card round. Remaining schedule: vs. Lions
