Umm, i dont think they would lose utterly.
And your b-league vs. a-league is nonsense, as the teams are never in the same league by default. Women's team is not in your "b-league" because they suck, y'know ? They are olympic champions of 2008 and 2012 and multiple world champions, so women's team by success is a-league. Triple a even, compared to male team.
