I believe Z said it was a gift of appreciation for Preston after over hearing Preston taking about how he wants that car, and how Preston last year apparently brought the
entire Packers' defense scooters for Christmas .
Aaron Rodgers has also talked about how it's been harder to have the normal team atmosphere and a normal locker room chemistry during Covid-19, with having divider walls up, where you can't understand the guy on the other side, when you used to be able to tell across the way with no problem.
And I think two other big changes have happened as well to effect the defense (or it might be one in the same), but the reports of Clark and the Smith Bros reportedly talking with Pettine and allegedly requesting or telling him to keep thing more simple.
And since the Eagles or Lions game, the defense has had tweaks, where the defense hasn't always been in full pass rush mode, but mixing it up more, at times clearly going more towards adding some clear run first play calls, where they aren't trying to pass rush or penetrate much, and mixing it up a lot more, which has clearly caught the OL off guard some, I think one of Keke sacks was the OL thought he'd be in run defense mode as he was on the plays before, but nope, he was penetrating on that play call.
Also, seems like they're trusting the CBs more to not have help over the top at all times, which is allowing them to use the Safeties a bit more aggressively, where Savage has shown up a lot more.
