In 2020, season will start in mid Feb in warm weather cities. Couldn't this year because of CBA and mandatory time off. Extra mid week games aside this year aside, this not only is going to help create a better playoff system but will help MLS teams in CCL
If this is the case that the case (big IF) then a mid-February opening should only be played in:
Miami
Orlando
Atlanta
Nashville
Dallas
Houston
LA x 2
Portland
Seattle
San Jose
(that brings me to 11)
I'm looking for another city where the average high temp is above 50 in February. Intern??
