The Dodgers have already declared their primary imperative for this winter. General manager Ned Colletti set the course Monday when he wasn't trying to tap dance around his manager telling everyone how dissatisfied he was with his contract."We could use a little younger group," Colletti said.The Dodgers were sort of moving in that direction even before the National League Championship Series, where they lost to a St. Louis Cardinals team that has 18 homegrown players, the most on a World Series roster in the wild-card era.
