Mild surprise: Detroit releases Buchanon

I'm a little surprised Detroit released cornerback Phillip Buchanon -- not so much because of his 2009 performance, which was disappointing, but because the Lions were already so thin at the position.

Their other primary starter last season, Will James, is a pending unrestricted free agent. I'm not saying the Lions' dreadful pass defense should return intact next season, but you need to feel relatively assured you can elevate your personnel before you start jettisoning your incumbent players.

Between the draft, free agency and a potential trade for San Diego's Antonio Cromartie, the Lions must feel pretty confident they can do just that.
