Backup QB Matt Leinart started 11 games for Arizona as a rookie in 2006 and five in 2007. But he has two starts since then, including the past two years with Houston, where new Raiders OC Greg Knapp was his position coach. “My mentality is I’m still confident that I can start, I’m still confident that I can play, and the good thing is that I know this offense so well, so I feel comfortable when I get my chance or I get the reps that I can execute it,” Leinart said Monday.
