GB having lost to KC helps us out. They'll beat the Cutler-less Bears - not that they wouldn't beat them with Cutler, just indicating that without Cutler the Bears have been horrid so GB really should be able to win that game with relative ease. For the Lions, this could be a huge plus because IMHO the Packers will not want to risk the Lions giving AR a concussion like they did last year as that drastically reduces their chances of winning in the playoffs. It would be Ludacris to play him vs Detroit with home field locked up and not playing for the perfect season. While I get they would like to take advantage of knocking out Detroit before the playoffs, the other side to that is they likely aren't that concerned due to the fact the Lions, Seahawks, or Cards have low chances of pulling off the upset in R1 and even if they do they will be going to Lambeau where Green Bay has to be the favorites by a considerable measure. And while the Lions are the division foe, it might be considered more advantageous to play them as they can more quickly prepare for them than the others.
Packers are also trying to get healthy right now, so they are more likely to lick wounds and come out refreshed for the playoffs. If Detroit wins Saturday, I could also see them doing the same as there would be little to play for vs Pack. That "highly anticipated" game could actually turn out to be more like an early Preseason game with a substantial amount of playing time for guys low on the depth charts, maybe even have guys from the Practice Squad brought up to replace someone who is "injured".
