Major League Soccer is preparing one of the most consequential structural changes in its three-decade history: a playoff expansion that could funnel as many as 20 clubs into the postseason, according to a report from the New York Post. The overhaul is tied directly to the league's impending move from a spring-to-fall calendar to a European-style summer-to-spring schedule, set to take effect next summer.
Twenty teams. In a league that currently fields 30 clubs, that would mean two-thirds of the competition advancing past the regular season. The sheer scale of that number demands scrutiny.
For context, MLS currently sends 18 teams to the playoffs — nine from each conference — in a format that already draws criticism for diluting the meaning of the regular season. Expanding to 20 would push that logic further, raising pointed questions about what separates a champion from a participant when the bar to qualify sits so low.
Proponents of expansion will argue it creates urgency deeper into the standings, giving mid-table clubs a genuine target to chase and keeping fan interest alive in cities where September form has historically felt irrelevant. There is something to that. In a league still fighting for cultural foothold in markets saturated by established sports franchises, manufactured stakes are sometimes better than no stakes at all.
But the competitive implications cut the other way just as sharply. A bloated playoff field rewards mediocrity. It allows clubs that spend carelessly, manage rosters poorly and underperform across 34-plus matches to buy themselves a second chance. For the organizations doing serious roster-building work — Inter Miami, LAFC, Seattle — that devalues the currency of a strong regular season finish.
The calendar shift itself is the more transformative variable. Moving to a summer-to-spring schedule aligns MLS more closely with global soccer's rhythm, which matters enormously for player recruitment, Leagues Cup logistics and the league's ambitions around Club World Cup and FIFA competition windows. The playoff restructuring is, in many ways, the downstream consequence of that larger realignment — administrators redesigning the competitive architecture to fit a new temporal framework.
What remains unclear is whether 20 teams represents a firm proposal or the outer boundary of internal negotiations. League executives have historically used round numbers as anchoring points before settling somewhere more defensible. Eighteen was already a stretch for many purists. Twenty would require a compelling structural argument to survive scrutiny from the league's more ambitious ownership groups, who have invested heavily in the premise that MLS is trending toward a merit-based model.
With the calendar change looming and the league set to welcome new franchises in the coming years, the playoff format MLS lands on will say something defining about what the competition actually values — depth of participation, or the integrity of a genuine title race.
