I'm not suggesting anyone start bombarding the guy with requests. Please don't anyone do that.Please don't volunteer Jeremy Crawford (or anyone else) for this job.
It is not our place as fans to go hunting for champions within WotC. If someone steps up, we can and should support that person; but we do not know enough about WotC's internal politics to identify a suitable champion, and we also do not have the personal relationship that would allow us to make the request.
