LOS ANGELES – Whether the Los Angeles Dodgers retain general manager Ned Colletti or fire him, the team is on a mission this offseason to find a way to get a younger roster while remaining competitive and to avoid signing any more bad long-term contracts. When you think about it, that's kind of the same thing.The Dodgers figure to be in the market for a starting pitcher this winter, but they are unlikely to pursue anybody who would receive a qualifying offer from their current team and thus cost the Dodgers a draft pick, a source indicated.
