Making sense of the Packers’ 2017 defense and this offseason’s personnel moves

Lately, I have been seeing this argument a lot about the Green Bay Packers’ defense:

#Packers fans in December:

“Gawd this defense sucks! Clean house! Fire Capers!”

Packers fans now:

“GAWD DONT REPLACE ANY OF THE PLAYERS ON DEFENSE!!”— Ross Uglem (@RossUglem) March 20, 2018

While Packer fans are as reactionary and hyperbolic as any fanbase out there, I wanted throw out some additional context. What the Packer front office has done is weird, it makes me question their self-scouting, and it makes me questions their understanding of what is and is not wrong with the team.
