Let's assume for a moment that Japanese right-hander Masahiro Tanaka is the best free agent starting pitcher available. Let's assume that the Dodgers are willing to wait for the new posting system between the Japanese and major leagues to be worked out, which might not happen until mid-December.Let's assume the Dodgers are willing to spend the $100 million or more it might take to sign Tanaka between the posting fee and his contract.How, exactly, would that work out?
