Arizona Cardinals quarterback Matt Leinart has been throwing at the team's training complex as he comes back from the broken collarbone that ended his season, coach Ken Whisenhunt said.

Whisenhunt, who was critical of Leinart on occasion, praised the way the quarterback handled the time he was sidelined.

"I'll say this for Matt, I'll give him credit, he's done a very good job during the season of working to stay up on the game and studying the game and doing the work in the classroom," Whisenhunt said. "Mentally, going into this offseason, not only does he feel better about our offense as far as what we're asking him to do, but I think his preparation is a lot better."
