Viking offense has some issues and it starts with their offensive line. THey have struggled for several weeks but last week against the Cardinals it finally hit them right in the face. The O line is not a very athletic one and it showed, but a few other things were exposed, the Cardinals made Percy Harvin a prioity and took him away as much as a defense can and challenged Bret to beat them on the outside. One other concern as i watched the tape of last weeks game, as i compare it to the start of the season for the Vikings, i felt Adrian Peterson was not the foundation of this offense. What i saw on tap was 3 WR formations and to many passes early. I know they got behind but even early AP was not the focus for the Vikings. If the Vikings want to get Bret back on track and avoid another clunker, they had better get the factorback (Peterson) going this week.
