Next will be interesting to see what Ben Johnson does. He does not seem like the type of coach that will rest people and concede anything, especially against DET.
A win in Week 18, the Bears would be locked into the #2 Seed with a game against GB.
A loss is basically a game against the loser of SEA@SF. So instead of GB coming back to CHI, you get either SF or SEA. SF is 7-2 on the road, SEA is 7-1 (would be 7-2 with loss to SF) while GB is 4-3-1 on the road.
So do you rest players all but guaranteeing a game against SEA or SF, or do you play everyone and go into a game with no rest while your opponent got a week off resting their players in Week 18 (GB resting players against MIN because they can't change their seeding)?
