INDIANAPOLIS — Last year, on the way to their 15-1 regular season, the Green Bay Packers would knock teams out with their offense. A game like Sunday’s against the Indianapolis Colts would have been over by halftime or early in the third quarter at the latest. Quarterback Aaron Rodgers, in his MVP season, would have made another back-shoulder to Pro Bowl receiver Greg Jennings. Or he would have connected with tight end Jermichael Finley on something down the seam. Or he would have hit receiver Jordy Nelson on a shot play down the field. And just like that, it would have been game over.
