I'm not going to research it but my recollection is that Terry Ryan embraced the phrase, if not actually coined it, and he resigned not too long afterward. That would be taking responsibility, unless I'm mistaken in what I remember.
I'm going to guess that research into the FO's comments about Paul Molitor when they came on board, compared to whatever they said when they finally fired him and brought in their own managerial choice, could contain some self-contradictions, but again it's not my research project and my plate's full enough at the moment.
