Cardinals vs. Vikings preview: Adrian Peterson's role, the Minnesota QB situation, Andre Ellington, Logan Thomas and more

The Arizona Cardinals take on the Minnesota Vikings on Saturday. Since the teams will not face one another in the regular season, this is the only opportunity to get to know good info from those who know -- the Vikings fans.

Part of our preview work includes a podcast already, but through a cool site Reply All, we also have a running conversation you can follow. Already, we have discussed Logan Thomas' performance against Houston, Adrian Peterson and his role in the new offensive system, what Andre Ellington's role will be and the Vikings' QB situation.

Here it is!
