John,
FWIW, in my tenures on the IESG and IAB, there were often folks who had a lot less long-term perspective on those bodies, the IETF, and the Internet than the Chairs and some who had as much or more. Unless we are willing to make the magical assumption, I don't think "Chair has knowledge and perspective, no one else is likely to" is really justified
This is also my view. The chairs are always very experienced (and I would expect them to be). I only have seen the workings of the IESG, but in general, there is always a mixture of people with different experiences in the organization. As a datapoint, there are 3 people in the current IESG with >5 years on the job and 3 people with half a year on the job (see http://www.arkko.com/tools/admeasurements/stat/adterm_4.html), and outside the IESG I count 10 people who are still active in the IETF with >5 years of IESG experience. Many of these people have experience from various other bodies inside and outside the IETF. And it could well be that a newbie to the IESG has far better views and experience about a administrative issues or even regular IETF attendee worries than someone who has dealt with the technical stuff for a long time in the IESG. I'd say there is enough expertise and experience to pick other people as well. For sure. Don't worry about it.
