Big picture, this team overall outplayed KC, and it's a shame they lost even with Love's struggles for most of the game. Usually when ML says a loss is his fault I think he's just trying to put the heat on his own shoulders, but in this case he was right. His major folly was keeping an Aaron Rodgers game plan in place for Jordan Love. Of course it was short notice but not anticipating those heavy blitzes and not adjusting until the 4th quarter was folly.
Beyond that, I can't get over how crummy KC looked. GB's offense looked like a machine where the gears were just not lined up right so it kept grinding to a halt. It's actually looked like that a few times with Rodgers, notably the first game of this season. KC just looked busted.
