A major drawback to google classroom is that a classroom must be created every year and assignments must be re-created every year. As teachers, we don’t teach the same way each year but the materials and resources remain fairly consistent. It would be nice if we could refer to these resources without the need to re-create the classroom and assignments. A way to work around the limitations is to have a Google site that accompanies classroom assignments. It doesn't have to be a Google site, but a Google site provides ready access to resources that are probably already on your Google drive.
