I thought the backbreaker yesterday was the holding call that negated Davis's 45 yard return. After that, the offense got backed up and then the Saints got the ball at midfield to set up the winning score. There's still a good chance they would have lost at the end, but the game likely would have remained close until then.

The penalty to take them out of FG range at the end of the 2nd half didn't help either.

All of these little things get magnified without Rodgers to make up for them.
