Why are the Vikings so bad on Defense

They actually aren't that bad, but they aren't that good either. They have played the pass fairly well. Antoine Winfield and Fred Smoot aren't pure shoutdown corners. But they have allowed less than 100 net yards passing the last two weeks. Corey Chavous is pretty-well prepared to play. Darren Sharper hasn't overly impressed since Week 1, but has overcome injuries. The Secondary isn't the Vikings problem, the only time it was, was against Cincy in Week 2 when they played corners 10 yards off the line.

The linebacking play has struggled especially in pass-coverage, they were terrible against Atlanta versus the Run. They do have some effective blitzers at the linebacker postion though.

They played well in Chicago. They lack discipline though against the run and on Pass Defense. The Vikings interior D-line has been pretty good against the run. Teams don't really run too-well up the middle versus the Vikings.

Their D-end play since Kenechi Udeze went out has been disappointing against the run. Lance Johnstone is primarily a pass-rushing specialist. Erasmus James is still raw, and Darrien Scott hasn't done much. Though the D gave up 3.2 ypr, yesterday. The key for the Vikings is pressure, and this is what is disappointing. They need to blitz-more with Brian Williams and the Linebackers? You ask won't the Vikings get burned? Maybe, but thier LB's don't cover anyone anyways.

The Key will be pressure, I think the Vikings D is closer than the Offense, I think this week versus Green Bay could speak, as how the Vikings do versus a very good offense. The Offense can't put the D in bad positions though like 1 and 3 yard touchdown drives like yesterday.
