I want it to be the Pack versus the Colts. I believe it is possible for GB to eek out a win in Seattle. GB's ground game should help to relieve some of the pressure on Rodgers, despite the calf.
However, I am not nearly as confident about young Andrew Luck maturing as a post season QB. It would be interesting to see him grow up before our eyes much like a young Eli Manning in the post season run to his first Super Bowl win.
So I say Pack vs the Pats.
