The Saints have signed 33-year old CB Mike McKenzie.  McKenzie played in 7 games for the Saints last season and he had 22 tackles, 1 tackle for a loss, 3 passes defensed and 1 interception.  McKenzie has now played in 133 games in his major league career and he has 470 tackles, 120 passes defensed, 1 sack, 1 forced fumble and 27 interceptions (4 returned for TDs).  This was a good move for the Saints who really have been ransacked by injuries in the secondary.
