No, that's not what I said. I said that if the White Sox failed to contend, then it would be fair to question the choice of La Russa, and if they win the WS, then La Russa would be considered the right choice. I did not say that if the White Sox make it to the playoffs but fail to win the WS, that that makes La Russa the wrong choice. (There's a Geometry logic lesson in there somewhere. )
FTR, the same would hold true of any manager that the White Sox hired, including my beloved, analytically driven, and much younger Alex Cora.
