When I was a kid, my dad always used to point out how the Boston Celtics (our favorite basketball team) seemed to trade for or sign star players from other teams when they were way past their prime. Something the Red Sox have done plenty of times in their history.
I remember being so excited, for example, when the Celtics got players like Artis Gilmore, Dominique Wilkins, and Xavier McDaniel only to be disappointed that they were old and broken down and not nearly as good as they had been when they were younger and played for other teams.
