I agree that there are more important concepts that need to be covered in freshman/intro level CS courses, but some of the graduates I was meeting and interviewing had not even heard of version control or source code management, let alone spent any time collaborating with a team of developers. They were not getting any exposure to it at any level within their program. It didn't even seem like something they had been introduced to. IMO, source control management should be as essential as ssh-ing into a remote server or running/compiling a program in the shell.
