The Minnesota Vikings Defensive Line

But the Packers have a very young D (besides the corners) starting to improve (you saw it in the 2nd game), as well as youth at WR and RB, that should be better. 

And even if the Vikings do improve and the Packers drop, remember, these teams weren't close last year.  There was 5 games between them and the Packers swept the Vikings, including in Minnesota, with a healthy AD and before Ryan Grant was in the lineup. 

hold up

even adding Allen and Williams the Vikings have defensive issues

not one of their LBs would start in GB or Chicago, yet three of them start for Minnesota.

Sharper is a ball hawk but he still misses a lot, and when he misses he is still the best end zone escort service in the NFL.

and Winfield is yet another year older and still only 3 apples tall.

are the Vikings better ~ YES

Allen will finally give tham a pass rush again, which they have lacked since John Randle left, and that will help everything. However I cannot see it propelling them into the top 10 defenses, more or less the #1.

The Vikes will still be the #3 defense in the NFC North
