On Friday night, the Dodgers will send Clayton Kershaw, the greatest pitcher of his generation, to the mound in Milwaukee to open the NLCS. To oppose the mighty Kershaw, the Brewers will send out their own ace: a 30-year-old righthander who throws 90 mph and is on his fifth team in the last four seasons. Jhoulys Chacin is no one's idea of a front-line starter.
