Yes the Packers offense forgot the system... the wide zone is created to take pressure off the QB (which LaFleur has stated a number of times).
What LaFleur normally doesn't mention is that this normally means making the RB the focal point though the run and short passes. The Packers did the exact opposite... and put all the pressure on the QB and the OL pass blocking even worse than Mike McCarthy did.
And this defensive skill talent is basically set up to pass rush with the lead ... not run defend from behind. As I said with LaFleur, I don't care whom the DC is, this team is not talent enough up front or at CB to be dominant and I have to give Clark and Lowry credit, at the end of last year they looked better than I thought they could (Lowry).
But the Packers are facing more wide zone offenses than ever before with 49ers, Rams, Seahawks, Bengals, Browns and Vikings... and Saints and Chiefs have offensive geniuses play callers.
But the Packers will go as their RBs go, as the RBs will take pressure off the QB and defense, giving them time to rest. Packers need to get that going.
Packers defensive will go as the opponent's OL goes and how much rest they get on the sidelines.
