As a Galaxy fan living in LA...awesome.
As someone who has lived in places with actual seasons....congratulations, you're going to do serious harm to attendance/desirability/value of the markets that deal with weather, which is a significant portion of this league. This would just further tilt things in LA & Miami's favor.
Winters in continental Europe don't compare to winters in Columbus, never mind Minnesota...and the places that do have comparable winters run the same kind of schedule the MLS currently does for obvious reasons.
Then again there's no good solution that doesn't involve the entire schedule shrinking. The current late February start doesn't factor in March being the snowiest month in a lot of places, nor are the playoffs in anyone's ideal time of the year.
This sounds like something that plays a hell of a lot better in a boardroom with a bunch of billionaire owners than it would with the fan actually paying to go to games. Just fix the damn transfer window. You don't need to immediately devalue half of the league to accomplish that.
Doesn't Japan, Australia and some places in Latin America use the same schedule as MLS for soccer? I don't know why they would change for more competition.
It's pure eurocentrism. Most of the Americas, as well as plenty others around the globe are on the same calendar year set-up as the MLS. The richest teams in Europe are on the Fall-Spring schedule, though, so that's the 'right' way to do it.
