Status: Free agent
Keep him because: He’s one of the best players in Major League Baseball, with a career .297 average and 241 stolen bases. His likely replacement in center field, Jackie Bradley Jr., showed he was not quite ready for prime time in 2013.
Let him go because: He’ll be extremely expensive and he wants a long-term deal. The Red Sox could also decide to give Bradley Jr. his shot at the full-time job.
