Don't know, can't get behind Sark honestly...his best season was just 9-4 at USC, handed a team that despite a 3 HC rotation had just went 10-4 the year prior.
Plus Washington isn't a bad place to coach, hell Tyrone Willingham had a bad stretch but before that there were some winning guys there. Rick Neuheisel (33-16), Jim Lambright (44-25-1) Don James (150-60-2).
I do however think Sark is hungry, possibly more so than any other name. He's an OA at Bama despite having been a HC at two major programs and a NFL OC. He could really be the best value hire available, if he's got his personal demons under control.
