your dad's old flannel shirt. Their strength of schedule currently sits at 32nd in the League. In their twelve games thus far, they have played only THREE teams with a winning record, ALL AT HOME (NE - L, SEA - W, MIN - W). They have already played the bottom four teams in total offense (Cards, Jets, Bills, and Dolphins), as well as the Lions (23) 2x, Giants (21), and Seahawks (19), giving some perspective to their high D ranking.
The only remotely balanced team they played all year is the Patriots, who beat them in Chicago.
