If you’ve watched the replay, it was not a legal screen….her feet weren’t set and she wasn’t squared up….i don’t think she was even trying to set a screen, she was moving backwards.
Taking a charge these days is pretty much just taking a foul because it’s going to be called a defensive foul. About the only charges that get called is when the defensive player just gets run through and in most cases, they’re not trying to take a charge.
