Lessons are to be taken from playoffs even for teams not in them (or maybe especially for teams not in them).
Two prominent ones are staring the Bears and everyone else in the facemask as the 2015 postseason opens this weekend and moves in the divisional round next.
The first is that defense still can wins championships. No AFC playoff team ranks worse than No. 11 (Pittsburgh) in scoring. Only Green Bay (12th) and Washington (17th) are out of the top seven, and one of those two will be gone after Sunday.
