The 2-0 Niners head into the contest after convincing wins against two of the NFC's most talented teams in the Green Bay Packers and Detroit Lions. After dealing with issues moving the ball downfield and scoring touchdowns via the vertical passing game in 2011, Alex Smith and his new crop of receivers have become more prolific, scoring an average of 28.5 points through two games.
The Vikings are 1-1 and will rely heavily on the legs of running back Adrian Peterson, who has made a fast recovery after suffering an ACL tear last season. He figures to have a tough time of penetrating the 49ers' stingy run defense. Minnesota will also be without wide receiver Jerome Simpson, who is serving the final game of a three-game suspension he received during the offseason for violating the NFL's substance abuse policy.
The betting lines for Sunday's tilt at The Metrodome are as follows:
San Francisco: -7
