On a long enough timeline, the survival rate drops to zero. In a 162 game schedule, the cream almost always rises to the top. For much of the season last year, it seemed like the White Sox would win the AL Central. They had the pitching to get it done, but the Tigers were a better team overall. Come September, they finally rediscovered the magic and took the division from the White Sox.
Jerry Reinsdorf kicked Kenny Williams upstairs and replaced him with Rick Hahn. Like an underperforming football coach, Reinsdorf felt the best course of action was to make Williams his president of baseball operations rather than firing him. I suppose it makes sense given how close they came to making the playoffs. However, he has been begging to be fired for years now, so we get to see if Hahn is going to be any better.
He is all but gone as the Sox turn to Tyler Flowers and the future. Probably for the best.
