I'm not too worried about the Packers. The Bills were playing in their Super Bowl. There's no hot rivalry with the Packers so I expect the Pats to do better.
The Bills defense just held the Pats to 25 points. The Packers defense just held the Rams to 29 points. And, the Packers actually have an offense.
The Packers game doesn't feel like any easy out to me.
