In the recent story I wrote for the Washington Post.com, I look at the offense around QB Brett Favre.
First, he's playing behind an offensive line that gave up 34 sacks last season, the Vikings didn't make any effort to improve it, and now he's even less mobile due to his hurting ankle. Second, RB Adrian Peterson's yards per carry keeps slipping every season. Third, WR Percy Harvin is finally back at camp but his migraine problems haven't gone away. And most importantly, they don't know when their best receiver, WR Sidney Rice, will return from his hip injury. That's a lot of question marks for one offense.
