Sorry if this has already been posted here or in another thread...did anyone see this article on NFL.com that was just posted a couple of hours ago? Here it is - interesting take on how the Vikings were preparing for the Niners (link to article: http://www.nfl.com/news/story/0ap1000000065796/article/how-the-minnesota-vikings-overtook-the-san-francisco-49ers?module=HP11_content_stream
A Vikings source explained why the team's offense was able to keep the 49ers off balance
"We studied them a lot this offseason, and we felt that some of their players felt it was all about getting sacks," the team source said. "Then they open the season with Green Bay and Detroit, who don't do anything but throw it, and they further buy into getting sacks. We decided we were going to run at them, and they didn't like it. After awhile, we feel like we broke them.
The plan early in the game was to "wham" block the 49ers' defensive linemen, especially All-Pro end Justin Smith, the source said. Since Smith tends to aggressively rush up the field, even against the run, the Vikings would send a trap blocker to level an unsuspecting Smith on a block that usually landed on his side. After awhile, the source said, Smith -- and other players -- started looking for the "wham" when it wasn't coming and receiving the block when he wasn't counting on it.
"We caught them off guard," the source said. "They didn't like that."
