HS All-Americans, man, guys on their way to D1. The vertical element of the game is not there for the women. Most rebounds are taken below the rim but when you have a big advantage you go vertical more often. Offensive rebounds would be an issue. Defending the rim would be an issue. The boys would also have more speed and explosiveness so defending the drive would be tough. I am not agreeing with people saying it would be a massacre but I do think HS AA level is sort of the tipping point where genetic difference becomes a determining factor.
