The 49ers are one of six undefeated teams left in the NFL and while they have already defeated two of the most prolific offenses in the league, they will face a different kind of test on Sunday.
San Francisco knocked off Green Bay in Week 1 and Detroit last week. Both teams are known for their high-powered offense. This week, San Francisco will face the Minnesota Vikings, a team better known for their strong defense. The Vikings are currently 12th in the NFL in yards per game allowed.
Asked what he saw from the Vikings defense of film, 49ers head coach Jim Harbaugh offered some high praise.
"Good defense, good defense. They are an attacking, aggressive defense," Harbaugh said. "They are a blitzing defense, a multiple-coverage defense. Very aggressive up front. It's a defense that's trying to get you into bad plays, bad situations and they've got the talent and scheme to be able do that."
One of the Vikings' biggest threats on defense is defensive end Jared Allen. While Allen is yet to record his first sack of 2012, he remains one of the NFL's most dangerous pas rushers. Allen racked up 105 sacks during his first eight seasons, including 22 sacks last season. He finished with six tackles, a sack and a forced fumble the last time he faced San Francisco.
