The Saints have signed 32-year old CB Chris McAlister.  McAlister played in 6 games for the Ravens last season and he made 16 tackles, defensed 7 passes and he had 3 interceptions.  He has now played in 135 games in his NFL career and he has made 427 tackles, defensed 137 passes, forced 1 fumble and he has 26 interceptions (five of which he has returned for TDs).  The Saints hope that McAlister still has something left so that he can help cover for Tracy Porter’s injury.
