David Caldwell's tenure as Jacksonville's general manager opened with him slamming the door on quarterback Tim Tebow.
He might do the same to Blaine Gabbert and Chad Henne.
Caldwell spent the majority of his NFL career in Indianapolis and Atlanta, learning firsthand the importance of having a franchise quarterback. Finding one for the Jaguars likely will determine the team's long-term success.
Caldwell says finding a QB can be difficult and not having one "makes it a lot more difficult."
He adds that you "don't necessarily have to have a franchise quarterback, but you have to have one that can win games for you."
The Jaguars have won just seven games the last two seasons with Gabbert, Henne and Luke McCown under center.
