Major League Soccer has taken the plunge.

The Board of Governors on Thursday in Palm Beach agreed to shift MLS’s calendar to a summer-to-spring season in 2027.

It is the most significant move the league has made in its 30 years, not just for teams and how they form their squads each season but also on fans and how and when they attend games.

The move aligns MLS with most of the major soccer leagues in the world, outside a few in South America. It is not perfect, and if you’ve been involved in the American game long enough, you’ve learned that there is nothing perfect in soccer. But founded by Alan Rothenberg and a small group of young advisors in the early 1990s on the concept of a single-entity, MLS has managed to evolve and grow on the basis of what is best for the collective.

“As the league continues to evolve,” MLS commissioner Don Garber said on Thursday when asked about the level of support for the calendar change, “we have to move collectively down a path where we are managing a shared and collective vision and the agreements that were associated with that.”

He said there was more support for the calendar change than he expected.

“That’s a positive but it was not necessary,” he added. “The level of due diligence our teams did, the level of support for understanding the transformational impact this move has on the overall enterprise, on and off the field, drove overwhelming support.”

The switch is about tradeoffs. Much of the focus has been on the winter months and the assumption that MLS will play through January, like most big European leagues do. But the new calendar might add one more week of league games in February than MLS plays now, starting in the third week of the month.

There will be tradeoffs and fans will be impacted.
