Link to January 3 FiveThirtyEight (Nate Silver's Political Calculus) column in the New York Times, "The Seattle Seahawks. Worst. Playoff. Team. Ever?"
At #6 of Silver's worst playoff teams ever (the 2010 Seahawks end up at #2) are the 1949-50 Sheboygan Red Skins. In the earliest days of the National Basketball Association — 1949-50 was the first season the league played under that monicker; before then it had been known as the Basketball Association of America — the league’s Western Division featured obscure expansion franchises like the Anderson (Indiana) Packers and the Waterloo (Iowa) Hawks. The Sheboygan (Wisconsin) Red Skins sneaked in to the playoffs at 22-40 despite a roster with only three players who had previous professional experience.
