The Cardinals have signed 26-year old safety Aaron Rouse.  Rouse played in 16 games for the Giants + Packers last season and he had 64 tackles, he defensed 4 passes and he had 1 sack.  Rouse has now played in 41 games in his three years in the NFL and he has 142 tackles, 11 passes defensed, 1 sack and 4 interceptions (173 return yards) with 1 TD.  Rouse is a physical run stuffing safety who once in a while makes a really game altering play against the passing game.  He should be a perfect hit with the physical defensive unit of the Cardinals.
