Looking at that, Bears did almost everything right
Except
For each carry we went twice as far as they did. That means we exerted less energy, and they would be more fatigued.
We turned them over a lot more than they did us.
We were amazingly more efficient in the red zone, which is how we nilled them in the second half.
When we did make a break, it looks like Bears missed quite a few tackles. That would be expected. If one player in defence fails in their job, it unravels quite quickly.
We appear to have been more able to reorganise our defence after a break by them than they were when we broke through. That is down to fatigue, plyer positioning, and morale.
