Matt Leinart obvious No. 2 after strong preseason

Posted: Updated:

TEMPE, Ariz. (AP) -- Arizona Cardinals coach Ken Whisenhunt won't say so officially, but Matt Leinart's strong preseason performance certainly seems to have erased any doubt that he's Arizona's No. 2 quarterback.

Whisenhunt says Leinart deserves a lot of credit because of all the criticism he has faced about his work ethic and off-the-field issues. The coach says Leinart has worked very hard to be a better quarterback and it's shown up in the preseason.

Leinart has been sharp from the beginning of training camp, and it's carried over to the preseason games.

He says he feels comfortable and confident when he's on the field.
