For the past lifetime, it's felt like the Packers have had a great offense and were hampered by their defense.
Thanks to a free agent splurge and heavy drafting, the defense has improved from abysmal to decent to actually pretty good over the last few years.
Entering 2020, the big concern was run defense, but, despite not adding defensive linemen, the unit improved from player development, coaching, and scheme tweaks. The Packers were a respectable 13th in the league (tied Washington), in rushing yards allowed. Outside of one Vikings game, the rush defense never really seemed like a major issue throughout the year.
