Free safety Oshiomogho Atogwe, the St. Louis Rams' top playmaker the last four seasons, became an unrestricted free agent Wednesday after the sides didn't agree on a multiyear contract.
The Rams had a late Tuesday deadline to sign Atogwe, who's coming off shoulder surgery that sidelined him for the final four games last season. The team declined to offer Atogwe a one-year tender for $6.976 million -- the player's 2009 salary, plus 10 percent.
"I love O.J," Spagnuolo said Wednesday. "The process took us to this point, but it's ongoing. I mean, we're still working at it and very hopeful, and we'll just have to see what happens these next couple of days."
"It's the reason why you have depth charts," the coach said. "You've got to have guys ready to go."
Atogwe was second on the team with 74 tackles last season, and he also had two interceptions. Craig Dahl, who started at free safety at the end of the season, is No. 1 for now, according to Spagnuolo.
"I recall him doing pretty good in a couple of games," the coach said. "I remember one of the mistakes, too. But steady and consistent."
"I feel like I am able to grasp concepts a lot better," Dahl said, according to the team's official Web site. " ... Here is a time where we really need to get picked apart, figure out what you need to get better at and what we can improve on as a defense. That's what we are looking to do here this spring."
