Viking running back Adrian Peterson showed his strong feelings toward NFL owners when he did an interview for Yahoo Sports.  Peterson compared the players' place in the game to "modern day slavery".  Peterson went on to say the owners make a lot of money off of them.  The NFL owners moved to lockout the players late last week after the players voted to decertify the players union.  One of the Vikings goals in the off season for the Vikings is expected to be signing Peterson to a contract extension.
