Bears currently #10. They can win next week and still draft 10th if GB beats MIN tonight and MIN beats DET next week AND LVR beats DEN next week.
If LVR beats DEN next week, the Bears can pick no worse than #11. The only team that can leap them is if the loser of GB vs MIN loses in Week 18. So if GB loses tonight, and to the Bears in Week 18, they would pick 10th. If MIN loses tonight and to DET, they would leap CHI.
If LVR loses to DEN next week, the Bears would pick no worse than #12.
So the Bears are locked into 10-12th right now with a win next week.
If they happen to lose, the best they could do is 8th (if NYJ and ATL win in Week 18), and no worse than 10th. So 8-10th.
OVERALL - 8th best pick, 12th worst pick
Not bad at all for a potential 8 win team in the hunt late in Week 17.
