Over on Twitter, @SteelCityStar is posting highlights from the Steelers/Broncos game from 1988. Among the interesting things about that game is that it was Tony Dorsett’s last game. That got me to thinking about those frequent, but still odd swan songs wherein a player, long associated with one team, finishes his career with another. Even when those changes make some kind of sense- Willie Mays leaving the Giants, but doing so to come back to New York to play for the Mets, or OJ returning to his hometown to play for the 49ers it’s still odd.
