Besides Tarvaris Jackson of Minnesota, there are six other non-rookie quarterbacks in the league who have logged fewer than 10 starts and either will be or have a chance to be No. 1 on their respective team's depth chart in 2007. Here's a look at the group:
• Derek Anderson (Cleveland): It actually might be Anderson, and not first-round choice Brady Quinn, who provides incumbent Charlie Frye the biggest training camp challenge for the starting job. A big, rangy passer with a strong arm and good accuracy, Anderson was 0-3 in late-season starts last year when Frye was injured. He completed 66 of 117 passes for 593 yards, with five touchdowns and eight interceptions.
• Jason Campbell (Washington): A first-round choice in 2005, the former Auburn star didn't get off the sideline as a rookie, but started the final seven games last season, posting a 2-5 record. In replacing Mark Brunell, he completed 110 of 207 passes for 1,297 yards, with 10 touchdown passes and six interceptions, for a 76.5 efficiency rating. Big in the pocket, very athletic and with a rifle arm, Campbell is set to be the Redskins' starter in 2007.
• Brodie Croyle (Kansas City): The former Alabama star, who might be a better player at the NFL level than he was in college, made only two cameo appearances as a rookie in 2006. The Chiefs' third-round choice completed three of seven attempts for 23 yards, with no touchdown passes and two interceptions. Assuming that Trent Green eventually is traded, Croyle will be given every opportunity to beat out journeyman Damon Huard for the No. 1 spot on the depth chart.
• Jay Cutler (Denver): Started the final five games as a rookie in 2006, after coach Mike Shanahan benched a struggling Jake Plummer and decided that Cutler's apprenticeship was over. In posting a 2-3 record, the former Vanderbilt star, the 11th player chosen overall in the '06 draft, completed 81 of 137 for 1,001 yards, with nine touchdown passes and only five interceptions. The unchallenged starter going into training camp.
• Cleo Lemon (Miami): Lemon is a long shot at best. Probably his only chance to start is if the Dolphins don't land Trent Green in a trade and Daunte Culpepper still isn't recovered from his knee problems. Lemon is a three-year veteran who has one career start. He does possess an advantage: He played for Cam Cameron when the new Miami coach was offensive coordinator in San Diego and knows the system. His career totals for four appearances include 38 completions in 68 attempts, 412 yards, two touchdowns and one interception.
• Matt Schaub (Houston): For all the attention he got while serving as Michael Vick's backup for three seasons, Schaub owns only two career starts and still is seeking for his first victory. The Texans paid dearly in the trade that brought them Schaub, who will replace the departed David Carr as the starter, so he'd better be as good as advertised. The former Virginia star has completed 84 of 161 for 1,032 yards, with six touchdown passes and also six interceptions.
