The Detroit Lions apparently are going to need some time to adapt to the departure of offensive coordinator Ben Johnson. Johnson left to become head coach of the NFC North rival Chicago Bears after helping the Lions win a second straight division title and score an NFL-leading 33.2 points per game last season. In their first game of the post-Johnson era, the Lions didn’t score a touchdown until 55 seconds remained in a 27-13 loss to the Green Bay Packers on Sunday.
