While no one expects Calvin to contribute right away, McFadden's exit creates an opening opposite Pro Bowler Dominique Rodgers-Cromartie. The early favorite to fill that opening is second-year corner Greg Toler. Toler struggled while adjusting to the speed of the pro game, but came on late last season and earned the confidence of the coaching staff. Toler's overall skill-set is quickly improving and he's on the short list for this year's most improved player.
Another player to watch in the Cardinals' secondary will be Michael Adams who enters his fourth season in Arizona. Adams has shined on special teams, but was relied upon heavily in pass coverage last season when injuries struck several players late in the year. Adams was picked on often, but performed admirably and will be most remembered for causing the game-clinching fumble against the Green Bay Packers in the playoffs. Adams will likely be in the mix for the nickel back throughout training camp.
The Cardinals looked formidable at times in pass defense during the 2009 campaign, but must work on being consistent in the secondary. Defensive coordinator Bill Davis has adequate talent at his disposal, but that talent will need to play well as a unit in order to progress accordingly.
