The Chicago D amazes me with how well they are playing. They average age on that defense is close to 30, and they have to have the oldest collection of linebackers in the league with their average NFL experience at nearly 10.
Offensive rank of first 5 opponents
Colts - 10th (Luck's 1st NFL start)
Their next opponent is DET, who is 3rd. Then
Looks like they will be feasting on shitty offenses all season.
