The Chicago White Sox are coming up on a long term period of sustained success. They did it by rebuilding the team from the ground up. They traded away Chris Sale in the middle of his prime for some prospects and the rebuild was off. They knew that some very tough years were ahead for them and they were right as they were pretty bad for three years.
Over the last three seasons, they were a really bad team that was routinely at the bottom of the American League standings. They used some high draft picks on some really good players and will undoubtedly use them in the near future to be a big part of the success.
