Sure, the entire baseball world knows that the White Sox are the worst team in modern major league history (forget the percentages, total losses are what people remember), but dig into the numbers a bit and 121 losses are just the little bitty tippy-tip of the iceberg.
Actually, we don’t have to dig into the numbers, because Baseball-Reference has done it for us. Scroll down far enough in their MLB team stats pages and you get to a position-by-position analysis of Wins Above Average. That’s average, not replacement, so the numbers are based on a hypothetical 81 wins rather than 47 or so, but the order of finish remains the same.
