Elite safeties are hard to come by in the NFL, but they truly make or break a talented defense. A great safety covers the field from sideline to sideline, helping in coverage and providing an extra "body" in the box against the run.

Despite suffering an injury last year, Atogwe has the ability to impact a defense in big ways, and several teams may regret the decision not to enlist his services.
So which teams could most benefit from adding Atogwe to their defense?
