I rather liked Hargrove and feel bad that he was fired.

And why would they sign Murray? His major appeal is that he is well known in Baltimore (and I don't even like him). Sure he has been a coach for a few years and even managed the Toledo Mudhens (or equivalent team which I am too lazy to look up), but that doesn't make him big league manager material. We are looking for an improvement over Hargrove, not just a change for change sake.
