Well, considering most of this board seems to think no viable outside candidate would work for Jerry, and put up with his "meddling" (though the hiring of Richard last year would seem to fly in the face of that belief), that leaves only people who don't have many other options but to take what they can get within the organization.
Regardless, Moore may well be an excellent choice. We've all heard for years how football intelligent he is, and since few successful coaches were successful players, there's no reason to believe he isn't qualified for the job. He knows the organization, and he's seen it from the bottom up, so he probably has a better feel for what needs to be done than anyone else could.
