They came out with an energy that has been lacking at the start of games, with the exception of this game and a handful of others, since Indy parted ways with Polian and Caldwell. Indy can ball but they often come out in a funk and then have to play from behind, instead of playing 4 quarters. I believe that the kickoff return was the accelerator that the team needed for a full 4 quarters of good football.
I wish you luck as well. I have known many Packer fans over the years and have not run in to one that I didn't like.
