The future of coach Jim Caldwell remains an important question for the Lions, who reshaped the organization last year by cleaning out the front office and hiring Bob Quinn from the Patriots as general manager. What was described as a country-club atmosphere has been turned upside down, and Quinn has taken a wait-and-see approach with Caldwell, who is signed through 2017. That means it will be time either to sign him to an extension or to replace him.
