Well according to my Packer friend the following needs to happen for the Packers to make the playoffs if the Giants win:
Should the Packers wind up in a tie with the Giants for the sixth and final playoff spot in the NFC, it will be broken through a strength of victory tiebreaker.
According to the NFL, the Packers can clinch that tiebreaker only if all of the following occurs on Sunday: Arizona wins at San Diego, Detroit wins at Dallas, Miami wins at Indianapolis, Minnesota beats St. Louis, San Francisco wins at Denver, Carolina loses at New Orleans, Houston loses to Cleveland and Tampa Bay loses to Seattle.
If Minnesota beats St. Louis and Detroit beats Dallas, there could be a tie between the Packers and Giants in strength of victory. It would take four of the other five outcomes for that to happen. Then the next tiebreaker would be strength of schedule, which the Packers have a slight edge in right now.
So first the Giants need to win.
Second if that happens, the Lions will not beat the Cowboys so our game really doesn't matter IMO.
According to NFL.com this is what needs to happen. Not all that stuff. Notice the OR's
