Bisciotti told the club's official website: "I think Joe deserves the benefit of the doubt. We saw the progression for five years. He has a down year, he throws a lot of picks. But Joe historically didn't throw a lot of picks.
"He's dealing with Marlon Brown and Pitta is gone and Anquan [Boldin] is gone. He's got Dallas Clark and Brandon Stokley. With all brand new targets, that's going to happen. I certainly look at last year as an aberration. I expect to see great things from Joe."
Flacco threw for 3,912 yards along with 19 touchdowns to 22 interceptions last season.
