Jeremy: Vikings Draft Talk

This morning I had a look at several different mock draft scenarios (http://www.nfldraftcountdown.com/sub/mockdraft.html, http://football.about.com/cs/nfldraft/a/bl_mockdraft.htm, http://www.sportsline.com/nfl/draft/mock) Five to be exact.
One mock draft had the Vikings taking Adrian Peterson with their 7th pick.
Two had Adrian Peterson being drafted before the Vikings pick at #7.
And still two others had the Vikings taking a player other than Adrian Peterson, when Peterson was still available with the 7th pick.
Confused yet?
Yeah, me too.
Several sources apparently have the Vikings taking Safety LaRon Landry out of LSU. And while Landry would be a great addition to the Vikings secondary, I think it would be a mistake to not address the offensive side of the ball with the 7th pick.
The first wish would be WR, and Calvin Johnson is clearly the best in the draft, but after Johnson the crop fall off considerably.
The next biggest question mark on the offense is quarterback. But I don't think for a second that Colonel Childress is going to draft a QB in the first round, because that would be the equivalent of him admitting that he may have made a mistake with Tarvaris Jackson.
So a young running back would be the next logical step. It would be nice to have someone to spell Chester Taylor so that Taylor doesn't put on so many miles this year, and wouldn't Adrian Peterson be a nice young building block for future Vikings offenses?
If Adrian Peterson is available with the 7th pick, and the Vikings pass on him, I think it will be the biggest mistake of the draft.
