The NWSL announced the format of the 2019 schedule in a press release today and dashed hopes we might get a longer pause for the World Cup than we had back in 2015. The league will take just 12 days off for the tournament, between June 3 and June 14; the World Cup takes place between June 7 and July 7.
A two-week-ish break might not sound so bad, until you sit down and think about a few other factors. First, that window is a Monday through a Friday, ie, only one actual weekend falls into it.
