Even though you felt you went to more meetings and therefore had a "broader view of the business", perhaps the project managers also attended meetings that you were not involved in, which gave them insights you could not have possibly known? For example, maybe during weekly PM meetings where all PMs gave an update of the projects they were managing, your PM also developed a strong sense of what was going on in the business? Maybe the PMs attended meetings where the corporate strategy was discussed, which you did not attend? Not recognizing that others may have vantage points that were unknown to me was a tough lesson to learn, but an important one. It's difficult to speculate on what someone else may know or not know.
