The St. Louis Cardinals were considered to be a consistent contending ball club not that long ago. The past few years have not gone according to plan in St. Louis, however, as the Cardinals have not reached the postseason since 2022. Regardless of whether or not they choose to rebuild, pursuing one specific free agent this offseason makes sense for St. Louis. As mentioned earlier, St. Louis clearly needs a reliable ace at the top of the rotation. What some may consider an over-pay could prove to be a steal for the Cardinals if Gallen returns to form.
