Give the Green Bay Packers this much: They won against every single team they should have beaten last season.
The Packers faced 11 teams that finished outside of the top 10 in Jeff Sagarin's rankings, and went 10-1. They lost to the Chicago Bears in the season finale as they sat starters in preparation for the playoffs, and it still took the Bears a last-second field goal to win. Winning every game (when giving normal effort) against non-elite teams is not easy. The NFL isn't college football. Every team is capable. You're not able to schedule Kent State in the NFL.
