Sam Keller and Rudy Carpenter form a dynamic quarterback duo at Arizona State that can't be topped. However, there are quite a few QB groups that provide coaches with options and defensive coordinators with headaches. Here are a few:

No team in the nation boasts a better one-two punch at the quarterback position than Arizona State's Keller and Carpenter. Keller has a stronger arm and is the fierier leader of the two, but Carpenter led the nation in passing after taking over for the injured Keller last season. The tandem combined for 4,438 yards and 37 touchdowns with 11 interceptions. Keller has reclaimed the starting position now that he's healthy, but Carpenter will be ready if called upon. Even if only used sparingly this fall, Carpenter still has two years of eligibility after the 2006 season to strut his stuff.
