I do not think that this is a must win at all. If you have been realistic about the team and
expect a 10-6 record like I do, it is the natural progression of records. I have them splitting
with the Bears and the Lions anyway as part of this 10-6 mark as I am sure many of you do. It just so happens that the ones away where i have them losing happens to fall at the early season time.
When looking at the early schedule, most people thought it would be quite difficult compared to later in the season. Thats why it does not matter going 0-3 in the NFC either as the losses are going to happen for everybody. Just happens earlier for the Pack.
For what its worth, i have them losing to Bears, Lions, Seahawks, Eagles, Saints and one more surprise loss - either Panthers, Pats, or Bills.
Anyway that is my take. The only thing that I feel will change this prediction is injuries or if somehow the team loses confidence because of this early play. It never has in the past though so i would not expect them to be down too long, although it would not surprise me at all for them to be 4-4 at the bye.
Like I said, just the way the schedule falls.
