According to the authoritative FanGraphs website, Red Sox centerfielder Jacoby Ellsbury is the top free agent position player on the market this Winter. Ellsbury and Robinson Cano are effectively tied at the top of the free-agent food chain—each with a 4.9 Wins Above Replacement score (WAR). Ellsbury has had a good enough 2013—albeit not with the power stroke he had in 2011—to command a silly multi-year offer from several teams. 'Super Agent Provocateur' Scott Boras will be sure to ratchet up the bidding war beyond what the Red Sox want to pay. Accordingly, they better hope Jackie Bradley, Jr. is for real.
