Revealing quote from Anquan Boldin:
Ravens receiver Anquan Boldin, who played with Leinart in Arizona, said he's not surprised that Leinart didn't secure the starting job.
"That's just because I've been there and witnessed the relationship between both Matt and Coach Whisenhunt," Leinart told 105.7 The Fan in Baltimore. "So I'm actually not surprised."
So far, Leinart has outperformed Anderson.
[Anderson] has completed 31 of 53 passes (59 percent) for 287 yards and two touchdowns, with two interceptions.
Leinart has completed 83 percent (19 of 23) of his passes, most of them short-range throws, for 161 yards and one touchdown with no interceptions.
The common accusation is that Leinart is settling for shorter throws than Anderson. Anderson, however, has a shorter YPA (5.4) than Leinart (7.0).*
As Boldin, and Leinart himself said, his benching has nothing to do with his performance and everything to do with the fact Whisenhunt doesn't like him.
*To give you an idea of how bad DA has played, Seattle ranked 24th in the NFL with 5.39 YPA last year. The Giants ranked 9th last year with 7.0 YPA.
