Two other leagues, the WUSA and Women's Professional Soccer, both came and went. But the NWSL has a smarter business plan, with the backing of the national federations from the United States, Canada and Mexico.
Canada came out with a great game plan, trying to slowing down games with a deliberate offense. Trouble was, it didn't make any difference against the U.S. women, who put the clamps on Canada's top scoring threats.
What led to the WPS suspending its season? Part of the problem was the league's shaky foundation, a problem that dates back to the professional leagu that preceded it, the Women's United Soccer Association.
