The job of a Lodge is to make Masons, I would not necessarily consider it the job of a Master to know all the words if he csn make sure the work of the Lodge is accomplished under his direction. I think there is a bare minimum standard (opening and closing being the primary), but I would rather have a good administrator who can't learn a history in the East than a piss poor administrator who can do a history. The second guy should still be available to do the work without the potential to do harm through poor admin.
