This was a signing to add veteran depth to the defensive line.  McKinley played in 15 games for the Broncos last year and he made 14 tackles, had 2.5 sacks and he forced a fumble.  He will come off of the bench for the Saints unless they suffer some more injuries.  McKinley has now played in 97 games in his NFL career and he has made 231 tackles, has defensed 3 passes, has 11.5 sacks and he has forced 2 fumbles.  This was a good move for the Saints.
