Twenty-seven years ago, Bendix was a 12-year-old diehard fan of a Cleveland team that lost the 1997 World Series to the Marlins on an extra-inning walk-off single in Game 7. The Marlins sold off their best players immediately thereafter and lost 108 games the following year, a turn of events Bendix remembers vividly. More teardowns followed.
