The past and future, realistically, is what the Tigers have to sell.The past because this is the 50th anniversary of the 1968 World Series championship team, and Alan Trammell and Jack Morris, heroes of the 1984 title team, will be inducted into the Baseball Hall of Fame this summer.The future because the Tigers have started to stockpile talent in trade deadline deals, and hold the first overall pick in the 2018 MLB Draft.
