With the return of SS Atari Bigby, to play alongside FS Nick Collins, the safety position is as solid as it has been all season. But the lack of depth behind the starters was exposed when Bigby missed 3 games.
Coming into the season, it looked like free agent S Anthony Smith would be the top backup, but he was surprisingly cut after the final preseason game. The backup job initially went to S Aaron Rouse, but his only start, the loss to the Bengals, was the final straw and they wisely decided to release him. Though he resurfaced with the Giants, and has become their starter, it's not because he's playing well. At this point, the Giants have no other options. The Packers also traded for S Derrick Martin before the season started, but he was bad in the Vikings game at Minnesota and hasn't played on defense since. Now he's suffered a concussion and it's not clear whether he'll be able to play next Sunday. After Rouse was released, they signed S Matt Giordano, but when asked whether Giordano was up to speed, McCarthy only said "he's been working." So apparently he's not up to speed. Now the Packers found themselves right back to where they started, and put a waiver claim in on Smith, but they lost out to the Jaguars.
Right now CB/S Jarrett Bush has to be the top backup for either safety position, and it's likely he's the best option of any the other backup candidates I've written about. Who's the best option at this point?
