Chad Pennington isn't the only quarterback the critics are closely watching. Here are four others whose maturity and consistency will be scrutinized well into the fall.
JOEY HARRINGTON, Lions. He has a rising star at running back ( KEVIN JONES), an improving offensive line and three supersized, athletic wide receivers ( ROY WILLIAMS, CHARLES ROGERS AND MIKE WILLIAMS) to make his job easier. And behind Harrington (right) is veteran JEFF GARCIA, ready and waiting to take over if he can't deliver.
JAKE PLUMMER, Broncos. It doesn't matter that he has a 19-8 record as Denver's starter over the last two seasons, or that he threw for a franchise-record 4,089 yards in 2004. Plummer still forces too many passes that lead to costly interceptions.
DREW BLEDSOE, Cowboys. The 33-year-old vet still holds the ball too long and his lack of mobility will always be a concern. JULIUS JONES and the other Dallas backs will be counted on to take much of the load off Bledsoe.
AARON BROOKS, Saints. New Orleans fans are losing patience with Brooks, who continues to play erratically despite a strong arm, nimble feet and game-breaking potential.
