It wasn't exactly a secret, given that the team is courting free agents Bob Sanders and O.J. Atogwe, but Buffalo Bills GM Buddy Nix is looking for an upgrade at the safety position.

"It went good," Nix said of Sanders' Tuesday free agent visit. "We gave him a physical and we said we're going to give it some thought and we'll look at it. We obviously need a safety and we'll get it one or the other."

It's unclear whether the Bills feel they need to upgrade at safety because they're unsatisfied with their personnel, or because of the impending free agent status of both Donte Whitner and George Wilson. Joe Buscaglia of WGR 550 asked Nix specifically if their courtship of Sanders and Atogwe meant that Whitner's Bills career was over.

"That's up to Donte," Nix replied.

Strong words from Buffalo's GM - not only toward Whitner, but about a position that was viewed as one of Buffalo's deepest throughout the 2010 season.
