The Cardinals lost Antrel Rolle, the Rams could lose Oshiomogho Atogwe and the 49ers might need to replace Michael Lewis. The Cardinals could also lose backup safety Matt Ware, who could draw interest from the Rams.
The Seahawks aren't exactly set for life at safety, either.
What to do?
Ryan Clark, Steelers. The 30-year-old longtime starter couldn't work out a long-term deal with Pittsburgh. The Cardinals are running their defense in the Pittsburgh mold. Clark could fit.
Brodney Pool, Browns. Teams generally do not sever ties with productive 25-year-old starters, but the Browns decided against tendering Pool as a restricted free agent after he suffered a series of head injuries last season. Pool picked off four passes in 11 games last season, making 10 starts before his season was ended.
Darren Sharper, Saints. The 34-year-old Pro Bowl choice would upgrade every secondary in the NFC West, but at what price? Sharper is probably most valuable to the Saints.
Jermaine Phillips, Bucs. Injuries have severely limited Phillips' contributions recently. It's probably not a great sign that Tampa thought about moving him to linebacker. Still, Phillips is 30 years old, hardly ancient by safety standards, and he has 74 starts.
Other safeties who are unrestricted free agents: Ware, Russell, Roman, Nick Ferguson, Sean Jones, Will Allen, Todd Johnson, Clinton Hart, Roy Williams, Vernon Fox, Marquand Manuel, Mike Brown, Tyrone Carter and Lawyer Milloy.
Also: ESPN's John Clayton notes that Jets safety Kerry Rhodes could be an option for Arizona via trade.
