The offense, despite any new wrinkles with the return of new coordinator Joe Philbin, will still run through Aaron Rodgers. There will be differences from years past, but the centerpoint remains the same.
On defense, new coordinator Mike Pettine has been tasked with finally getting the Packers defense to produce on a consistent basis. Since winning a Super Bowl in 2010, Green Bay's defenses have peaked in the middle of the pack, or worse.
One of the culprits of last year's defense was their inability to get off the field. Part of that problem was that the offense struggled with Rodgers out and the defense spent more overall time on the field to begin with.
