Attendance figures for the second North American Soccer League, which came to be after a breakup between what was then the USL First Division and the Team Owners Association (TOA) over how USL was run and the disposition of Nike’s sale of the league to NuRock instead of Jeff Cooper. This league lost USSF Division II sanctioning for 2018 and opted not to go forward as a Division III league. What remains of it has sued Major League Soccer and the United States Soccer Federation on antitrust grounds.
