To be fair, one of the Vikings biggest problems the past 4-5 seasons has been their O-line. I praised Spielman's offseason moves to shore that up, especially with the Alex Boone signing. However, their average O-line was decimated by retirement and injuries much like our defensive backfield. Exacerbating the problem is that Norv hasn't figured out how to compensate for the lack of running game and keep defenses from aggressive pass rushes. Like it or not, Mike McCarthy and Rodgers have done much better at it....maybe just from having to do it in 2011 and other lean years, but they are better at it.
The Vikings defense seemed to lose all it's air on two plays: the first Jordan Howard run and the missed INT by Xavier Rhodes. After that the Bears just continued to move the ball at will. Let's also not avoid giving credit to Cutler. While he had some inaccurate throws in the beginning and miscommunication, it was probably the best game that I've seen him play. The ball had more zip and was on target in tight quarters. It was like he was wearing his old Denver jersey for one day.
