ALLEN PARK, Mich. (AP) - Detroit Lions coach Jim Caldwell says he took players out to dinner during the offseason to serve them better as their leader. Caldwell believes coaching is a service business. Jim Schwartz never seemed to say anything like that during his five years with the Lions. Caldwell has had a calming presence on his new team and at least a couple players say his approach is a refreshing change. Schwartz was emotionally charged on the sideline - and infamously on the field during one postgame exchange with San Francisco coach Jim Harbaugh - and his ways appeared to wear on executives and players. He was fired following last season's flop and Caldwell was given a second chance to lead an NFL team.
