Newly signed OLB Quentin Groves will provide much needed depth behind expected starters Sam Acho and O'Brien Schofield, though he could challenge for a starting spot. With Joey Porter not expected to return and FA Clark Haggans still unsigned, the Cards have only untested veterans Brandon Williams, Antonio Coleman and undrafted rookies Zach Nash and Broderick Binns for depth. Stewart Bradley has played OLB but is expected to play mostly ILB this season.
