Atogwe, who will turn 31 next week, spent last season with the Redskins and was generally thought to have been slowed by injuries (but slowed nonethless). Given his recent injury history, this is no minor concern. He's had shoulder (2009), knee and toe (2011) issues in recent years.
But if he is healthy, he'll provide the Eagles with some much needed veteran insurance at the safety position. At his best he was a savvy, instinctive guy and a good tackler. Playing in a more limited role here could be a benefit to both him and the team.
Atogwe has generally played FS in his career, but in the Eagles' system could probably provide cover at either position. He spent last season with the Redskins, but was cut in March.
All that said, nothing has made him more famous in BGN land than his glorious publicity shots (which is actually now his google profile) in which it appears as though he's either really confused or never ready for the picture to be taken...
