Chris Carr the Vikings' latest value DB

When we last checked in on the Minnesota Vikings' defensive backfield, they had signed free agent cornerback Zack Bowman to a one-year contract and were continuing to fulfill the mantra of new general manager Rick Spielman: "Value" players from free agency and blue-chippers from the draft.

That's the way to view their latest move, a one-year deal with free agent Chris Carr that the Jason La Canfora of the NFL's web site first reported Wednesday. Carr was a full-time starter for the Baltimore Ravens in 2010 but appeared in only nine games, and 17.5 percent of the Ravens' defensive snaps, in 2011 because of a hamstring injury. He'll turn 29 later this month and will join a crowded if underwhelming group of contenders for the Vikings' 2012 cornerback rotation.

Carr and Bowman will compete for time with holdovers Antoine Winfield, Chris Cook and Asher Allen. If you were hoping for a more significant addition, then I would suggest looking toward the draft. That's where Spielman has said his best players will come from, and it's fair to hold him to that assertion.
