There is a strong element of GM speak here. The Jaguars are promoting competition above all else, and Caldwell is saying that Kafka will get his chance to make noise.
There also should be a recognition that this sort of statement would not be made in other cities with better quarterbacks. If Gabbert or Henne really impressed this new Jaguars staff, a journeyman picked up in the middle of June would not have a chance to become a starting quarterback. Practice reports out of Jacksonville this offseason haven't been overly kind.
