The committees don't actually make the hire. They make a recommendation to the person who does (Wilson).
Also, the chair of the committee is usually not the person who will supervise the person hired.
This committee consists of:
A coach
A former player
A current player
Two associate athletic directors
Two alumni (Lawyer and Judge)
And is chaired by a professor who is a faculty representative to the athletics program who is a long time member of the athletic board:

I don't see anyone on the committee that doesn't make sense.
For those who have listed a few other alumni...you can't be on a committee if you are unable to devote time to attend meetings. Not being on the committee does not mean that they cannot be consulted for input.
As for the process, the committee will:
1) Determine the qualifications they are looking for.
2) Seek candidates. (This can be through contacting or advertising)
3) Evaluate the candidates who submitted resumes/applications/ or otherwise applied. From this they determine which candidate(s) to interview and the format of the interviews.
4) From those interviewed, determine which, if any, candidates to recommend to Wilson. The committee chair will write up the reasoning for the candidate they selected.
It sounds a lot more complicated than it really is.
