SS Atari Bigby, Green Bay Packers — He appeared in only four games in 2010 after an ankle injury landed him on the PUP list before the season, but he was a play-making strong safety in both 2007 and 2009 and still has starting talent.
SS Roman Harper, New Orleans Saints — Harper got torched by the Seahawks in the playoffs and coverage is not his strong suit, but he's a good tackling strong safety and forced an incredible six fumbles in 2010. He's still just 28 and has starting ability.
FS Danieal Manning, Chicago Bears — A dangerous kickoff returner, Manning has never quite developed into the quality safety the Bears had hoped he'd be when they drafted him in the second round in 2006. He has the physical tools and is still an intriguing prospect at 28.
SS Quintin Mikell, Philadelphia Eagles — Mikell has been a solid yet unspectacular starting safety for the Eagles over the past four seasons. At 30 and without any standout abilities, he primarily profiles at a short-term starter or veteran backup.
SS Paul Oliver, San Diego Chargers — A supplemental draft pick out of Georgia in 2007, Oliver has seen increased playing time in each of his four pro seasons and continues to get better each year. He started eight games in 2010 and has more growing to come.
SS Bernard Pollard, Houston Texans — His whopping 213 tackles over the past two seasons is not all that impressive when you realize the guy is the worst starting safety in the NFL when it comes to coverage. It won't take long for teams to figure it out either, and he probably only has a few more years of starting before the entire league realizes he's just complete enough.
FS Brodney Pool, New York Jets — Concussions have always been his big issue, but he's always been a solid safety and did a solid job in Rex Ryan's defense in 2010. He should be able to compete for a starting job elsewhere and still has room to grow.
FS Darren Sharper, New Orleans Saints — Talent-wise, Sharper should easily crack the top five mentioned previously in this article. But the long-time playmaker is 35-year-old and missed much of last season with knee issues, making him only a short-term fix for any team.
FS Eric Weddle, San Diego Chargers — Weddle offers a good blend of hard-hitting, run-stuffing ability and some decent coverage skills. He's an underrated and versatile safety with the intangibles to get even better.
SS Donte Whitner, Buffalo Bills —Whitner racked up a ridiculous 140 tackles in 2010 and was one of the biggest culprits in Buffalo's 24th-ranked defense in 2010. He has never really lived up to where he was drafted and will have to fight for chances to start elsewhere.
FS George Wilson, Buffalo Bills — A converted wide receiver, Wilson was relegated to a backup role in 2010 after totaling 103 tackles and four interceptions as a starter the year before. He's worked extensively at both safety spots, but it doesn't bode well for him the team started Whitner over him and Wilson probably profiles more as a backup and special-teamer.
