WPSL. UWS. USL W. WISL. It’s easy to get lost in the scattered acronyms of the lower leagues of women’s soccer in the United States, leagues that have existed in various states off and on for decades now. Some of them resemble loose confederations of regional rivals, like WPSL. Some of them, like WISL, don’t even exist yet. What they all have in common is a desire to strengthen the footholds women’s soccer has in the U.S., and all on comparatively meager budgets.
