Wallace threw for more than 1,500 yards, finishing with 11 touchdowns and just three interceptions while starting eight games for Seattle last season, with Matt Hasselbeck out because of bulging disk in his back. Wallace completed 58 percent of his passes. The Seahawks finished 3-5 in games Wallace started last season.
"You always have to have confidence that you can come in and be the starter on any team," Wallace said. "I always feel that way. I'm adamant about it. And I'm going to keep working to improve each day, and hopefully something happens."
Still, Wallace is considered by most league observers as a solid backup with good athleticism that could provide an added spark for a team by running the Wildcat offense.
Wallace, 28, is signed by Seattle through the 2010 season and due to make a base salary of $1.75 million in 2009 and $1.5 million in 2010.
The Seahawks tried to use Wallace as a receiver in 2008 after injuries depleted the position, but Wallace injured his calf during warm-ups before the San Francisco game at Qwest Field, and limped through the first half of the season.
Hasselbeck has said he's healthy heading into this year's training camp, which means there is a possibility Seattle may try to get Wallace on the field in another capacity.
If that is the case, offensive coordinator Greg Knapp has not told Wallace yet, letting him instead get comfortable with the new offensive system during offseason workouts.
"As soon as we come back and start getting into training camp maybe, but right now we're not doing too much," Wallace said about the possibility of playing other positions besides quarterback. "We're just trying to grind through this offense, trying to learn the offense and see where it takes us from there.
"It's a new scheme for everybody. So every time we come out we're trying to get better. Mistakes are going to happen in a new system. But you just try and push those behind you and not keep making the same mistake twice."
