Biggest surprise: There weren't any big ones. Undrafted rookie linebacker Reggie Walker did beat out veteran Victor Hobson. The team kept seven receivers for now, including Lance Long, after injuries affected Early Doucet, Anquan Boldin and (previously) Steve Breaston. I would not expect the Cardinals to keep seven receivers all season, a reminder that this is the team's initial 53-man roster, not the final one.
Arizona sought to upgrade its secondary through the draft and free agency. That spelled the end for veteran safety Aaron Francisco. I thought the team might keep veteran center Melvin Fowler as insurance. Rookie returner LaRod Stephens-Howling stuck around, costing fullback Tim Castille a chance to continue with the team. Tight end Leonard Pope's demise had been on the horizon for a while and it was a bad sign when he was playing deep into the second half of the fourth exhibition game.
No-brainers: The team also released quarterback Tyler Palko, receiver Steve Sanders, receiver Ed Gant, cornerback Wilrey Fontenot, running back Chris Vincent, cornerback Jameel Dowling, fullback Reagan Maui'a, guard Trevor Canfield guard Carlton Medder, defensive end Alex Field, defensive tackle Keilen Dykes, tackle Oliver Ross, receiver Onrea Jones, defensive tackle Rodney Leisle, linebacker Chase Bullock and linebacker David Holloway. Canfield, chosen in the seventh-round, was the only 2009 draft choice released.
What's next: The heirarchy at tight end will continue to shake out, with Dominique Byrd essentially getting an extended tryout while Ben Patrick serves a four-game suspension. The team still could use a backup center with some experience.
