MLS is in the midst of its most aggressive growth period. Consider that for a stretch from 2015-2022, only one of those years (2016) will have not included the addition of at least one expansion team and the league will have grown from 18 clubs to 30.
FC Cincinnati, the 2019 addition, is slated to open its new stadium next year. Inter Miami and Nashville SC just began life in the league this past week, with each showing some promise but ultimately falling in one-goal defeats in their respective debuts. Their long-term stadium solutions are both in the works.
