Josh Hamilton played for the Reds for one season, but he could leave quite a legacy in Cincinnati, as the central figure in two of the best deals of this decade. Hamilton languished for years in the Rays' system, sabotaging his career with substance abuse, limited to 23 games above Class A, and yet the Reds acquired him in the Rule 5 draft before last season.
He was a feel-good story. He hit .292, with 19 home runs in 90 games, and he shared his saga of personal failure and rehabilitation with anyone who asked. But baseball is a business, and the Reds needed pitching, so they traded Hamilton to the Rangers for Edinson Volquez.
