Brian St. Pierre has been really good in the preseason for the Cardinals solidifying his role as the #3 QB on the team.  St. Pierre has completed 16 of 22 passes (72.7%) this preseason for 124 yards with 1 TD pass and 0 interceptions (101.3 QB Rating).  He has also carried the ball 2 times for 15 yards (7.5 ypc).  St. Pierre was brought over last season by head coach Ken Whisenhunt who coached him in Pittsburgh so the coach thinks he can do a good job if Leinart and Warner both went down to injury.
