The Dolphins have signed 27-year old CB Evan Oglesby.  Oglesby played in 9 games for the Ravens last season and he made 14 tackles.  He has now played in 4 years in his NFL career appearing in 36 games in which he has 35 tackles and 2 passes defensed.  This was a decent signing as Oglesby will provide depth in the secondary and he will likely help out on special teams.
