After that, had you kept watching, you'd see that Green Bay frustrated Manning. Also, keep in mind they were playing without several defensive starters - Clay Matthews and Al Harris, most notably. You are not going to stop the Colts anyway - you just have to slow them down and stop them some of the time.
I am worried about Green Bay's defense, but it has nothing to do with that. Their run defense is suspect and they have difficulty rushing the passer aside from Clay Matthews. They are getting older at the corner positions, and I fear they will give up too many big plays. You only hope they can create as many big plays defensively as they give up. Keep them in the ball game is the idea for that defense, because the offense is going to light it up.
