Not counting ties, there are four possible scenarios in our division in Week 17:
1. Hawks and Rams both win. 2. Hawks win, Rams lose. 3. Hawks lose, Rams win. 4. Hawks and Rams both lose.
Scenario 1: The Hawks are currently 8-7, the Rams 9-6. We both win in Week 17, we go to 9-7, Rams 10-6. We could tie the Rams if we beat them in Week 18 as both teams would finish 10-7, both would be 4-2 within the division, and both of us would have 6-6 conference records, which would throw the tiebreaker to the strength of victory.
Scenario 2. If we beat the Bears and the Rams lose to the Cards, we will go to 9-7 while the Rams would be drop to 9-7, putting us in a tie. That would make Week 18 vs. the Rams for the divisional championship.
Scenario 3. If we lose to the Bears and the Rams beat the Cards, we drop to 8-8 while the Rams would go to 10-6, a two game lead with one to play. They clinch the division.
Scenario 4. If we lose to the Bears and the Rams lose to the Cards, we drop to 8-8, the Rams drop to 9-7. That would make Week 18 relevant as if we were to win, we'd both finish with 9-8 records and the tiebreakers would apply.
The Bears game is relevant to the playoffs. I don't understand why this is an issue.
