Outside of expansion, the relegation and promotion system used around the world is the most discussed MLS topic throughout the years. There are many points both for and against the structure at this junction in the league’s growth.
Those in favor point to the way soccer/football is built around the world, increasing the interest in the bottom of the table, and overall interest as small clubs have a chance to advance upward.
While, opponents to the move would point out the huge investment made my recent expansion sides and their fear of dropping, or that second tier teams and stadiums aren’t built for MLS standards yet.
