However they build the quarterback group, Matt Leinart will have to work to be the No. 1.
"I think everybody on our team knows that they've got to play and play well to keep their positions," Whisenhunt said. "It's hard to say Matt has to earn it now because he's the only quarterback on our roster. There is no secret we've got to address that. We've got to get more depth at that position.

As far as building through the draft, the Cardinals are going to take the same approach they've taken since Whisenhunt's arrival.
"We're going to continue doing what we've done in the draft, as far as evaluating personnel and taking the best player available who fits what we do. We've had great success with that and that's the way we'll continue."
Perhaps Tim Tebow could be that guy, perhaps not. Despite every ounce of Tebow criticism, people seem to be fascinated with him. Whisenhunt will be watching.
"He's an interesting guy," Whisenhunt said of Tebow. "I think the one thing you can't overlook is he has been very successful in college football. He's won a lot of games, and there's a lot to be said for that. So I think the transition for any player moving to this level is going to be difficult to a degree. For Tim, because of the offense that they ran, there is going to be a transition period. One thing I'll say about him, he's a very good athlete and he's done a lot of things for that offense.
"I'm excited to see what he does this spring in his workouts and how he adapts to the pro style things he's going to be asked to do. It's going to be interesting to see where it goes."
