The Packers seeing this, thought it would be the ideal defense to run against (it usually is based on math alone). First snap, hand the ball to Eddie Lacy, three yard gain. Second snap, hand the ball to Eddie Lacy again, fumble, Lions pick up the fumble and score a TD. The next series the Packers again ran the ball their first two plays without much success.

You know when Rodgers & Co. saw that single-high defense, they all began to smile ear to ear knowing very well their fortunes would change this week. They love that coverage because they know that can eat it up with timing routes like the slant-flat route combination that Jordy Neslon and Aaron Rodgers have mastered over the years ( third Screen shot).
Solution? Skip the run (unless you want to run zone and put Starks in), put in Harris and throw it to middle of field and the flats.
