IMO candidates for a UW head coach should have the following on their resume:
1) History of success as a head coach.
2) Experience as an assistant or coordinator under an elite coach and at a top tier program or an NFL team.
I do not think those are unreasonable.
I agree with #1 but don't give a flying fuck about #2. I'd change #2 as has demonstrated to be a successful coordinator at other schools.
I like Tim DeRuyter not only because of his head coaching W-L but also because every school he has coached at as a DC he improved them over night. These weren't your stacked programs like Sark/Kiffin had USC either.
In fact as a past coordinator I'd rather the coach have coached at a school where he had success but at a school where he didn't have the best talent week in and week out like Sark/Kiffin/Holt/Chow did while at USC.
